multiple traditional mcu-based system components with one, low cost single-chip programmable device. psoc devices include configurable blocks of analog and digital logic, and programmable interconnects. this architecture enables the user to create cu stomized peripheral configurations that match the requirements of each individual application. additionally, a fast cpu, flash program memory, sram data memory, and configurable i/o are included in a range of convenient pinouts and packages. the psoc architecture, as shown in the logic block diagram on page 1, is comprised of four main areas: psoc core, digital system, analog system, and syst em resources. configurable global buses allow all the device resources to be combined into a complete custom system. each cy8c24x23a psoc device includes four digital blocks and six analog blocks. depending on the psoc package, up to 24 general purpose i/o (gpio) are also included. the gpio provide access to the global digital and analog interconnects. psoc core the psoc core is a powerful engine that supports a rich feature set. the core includes a cpu, me mory, clocks, and configurable gpio (general purpose i/o). the m8c cpu core is a powerful processor with speeds up to 12 mhz, providing a two mips 8-bit harvard architecture microprocessor. the cpu uses an interrupt controller with multiple vectors, to simplify pr ogramming of real time embedded events. program execution is timed and protected using the included sleep timer and watchdog timer (wdt). memory includes 4 kb of flash for program storage and 256 bytes of sram for data stor age. program flash uses four protection levels on blocks of 64 bytes, allowing customized software ip protection. the psoc device incorporates flexible internal clock generators, including a 24 mhz imo (internal main oscillator) accurate to 4% over temperature and voltage. a low power 32 khz ilo (internal low speed oscillator) is provided for the sleep timer and wdt. if crystal accuracy is desired, the eco (32.768 khz external crystal oscillator) is available for use as a real time clock (rtc) and can optionally generate a crystal-accurate 24 mhz system clock using a pll. the clocks, together with programmable clock dividers (as a system resource), provide the flexibility to integrate almost any timing requirement into the psoc device. psoc gpios provide connection to the cpu, digital, and analog resources of the device. each pin?s drive mode may be selected from eight options, allowing great flexibility in external inter- facing. every pin also has the capability to generate a system interrupt. digital system the digital system is composed of four digital psoc blocks. each block is an 8-bit resource that can be used alone or combined with other blocks to form 8, 16, 24, and 32-bit peripherals, which are called user modules. figure 1. digital system block diagram digital peripheral configurations include: pwms (8 to 32 bit) pwms with dead band (8 to 24 bit) counters (8 to 32 bit) timers (8 to 32 bit) full or half-duplex 8-bit uart with selectable parity spi master and slave i 2 c master, slave, or multi-master cyclical redundancy checker/generator (16 bit) irda pseudo random sequence generators (8 to 32 bit) the digital blocks can be connected to any gpio through a series of global buses that can route any signal to any pin. the buses also allow for signal multiplexing and for performing logic operations. this configurability frees your designs from the constraints of a fixed peripheral controller. digital blocks are provided in ro ws of four, where the number of blocks varies by psoc device fa mily. this allows the optimum choice of system resources fo r your application. family resources are shown in ta b l e 1

analog system the analog system is composed of six configurable blocks, each comprised of an opamp circuit allowing the creation of complex analog signal flows. analog peripherals are very flexible and can be customized to support spec ific application requirements. some of the common psoc analog functions for this device (most available as user modules) are: analog-to-digital converters (up to two, with 6 to 14-bit resolution, selectable as incremental, delta-sigma, and sar) filters (two and four pole band -pass, low-pass, and notch) amplifiers (up to two, with selectable gain up to 48x) instrumentation amplifiers (one with selectable gain up to 93x) comparators (up to two, with 16 selectable thresholds) dacs (up to two, with 6 to 9-bit resolution) multiplying dacs (up to two, with 6 to 9-bit resolution) high current output drivers (two with 30 ma drive) 1.3v reference (as a system resource) dtmf dialer modulators correlators peak detectors many other topologies possible analog blocks are arranged in a co lumn of three, which includes one ct (continuous time) and two sc (switched capacitor) blocks, as shown in figure 2 . figure 2. analog system block diagram acb01 block

include a multiplier, decimator, low voltage detection, and power on reset. brief statements describing the merits of each system resource follow: digital clock dividers provide three customizable clock frequencies for use in applications. the clocks can be routed to both the digital and analog systems. additional clocks can be generated using di gital psoc blocks as clock dividers. a multiply accumulate (mac) provides a fast 8-bit multiplier with 32-bit accumulate, to assist in both general math as well as digital filters. the decimator provides a custom hardware filter for digital signal processing applications including the creation of delta sigma adcs. the i 2 c module provides 0 to 400 khz communication over two wires. slave, master, and multi-master modes are all supported. low voltage detection (lvd) interrupts can signal the application of falling voltage levels, while the advanced por (power on reset) circuit eliminates the need for a system supervisor. an internal 1.3v voltage reference provides an absolute reference for the analog system, including adcs and dacs. psoc device characteristics depending on your psoc device characteristics, the digital and analog systems can have a varying number of digital and analog blocks. the following table list s the resources available for specific psoc device groups. the psoc device covered by this data sheet is
