| ALDEC 8051 IP Core Data Sheet April 11, 2006 (version 1.0) Overview The 8051 core is the HDL model of the IntelTM 8-bit 8051 micro controller. The model is fully compatible with the Intel 8051 standard. Features Opcode and Cycle Equivalent to Intel standard 8051 Support for Intel Hex file format Up to 4K Bytes Internal Program Memory (ROM) Up to 128 Bytes Internal Data Memory (RAM) Up to 64K Bytes External Program Memory address space Up to 64K Bytes External Data Memory address space Up to 128 Special Function Registers (SFR) 32 bi-directional and individually addressable I/O Lines Two 16-bit timer/counters Full Duplex UART (Serial Port) 6-Source/5-Vector Interrupt Structure with Two Priority Levels Pinout Table 1: Core Signal Pinout Name CLK EA 2) 2) 2) 2) 3) 3) 3) 1) Direction Input Input Input Output Output Bidirectional Bidirectional Bidirectional Bidirectional Polarity Low High High Low Clock input External Access Description RST ALE Synchronous reset Address Latch Enable Program Store Enable Port P0 Port P1 Port P2 Port P3 PSEN P0[7:0] P1[7:0] P2[7:0] P3[7:0] 3) Notes: 1) XTAL1 and XTAL2 original device pins were replaced with one CLK (clock) input signal. The clock frequency value has no limitations during the functional simulation. 2) EA, RST, ALE and PSEN signals behave exactly the same as the original device and are compatible with the Intel 8051 standard. 3) In the synthesizable model, each bidirectional pin is defined in the core interface as two separated VHDL ports. Optionally, using the Aldec VHDL/Verilog Interface, it can be merged to one bidirectional VHDL port. The behavioral model has bidirectional ports. www.aldec.com (c)2006 Aldec, Inc.
