32M-bit Mask ROM
1.
INTRODUCTION
The SNR032 is a signal power, 32M-bit, read only memory. It is organized as 4M bytes, operates for single 3V power supply, support static standby mode. The SNR032 embedded two different interfaces, one is a standard 8-bit/16-bit interface bus which compatible with SNL310, another one is a special 8-bit AD (address/data) bus which compatible with SNC710. SNR032 offers automatic power-down, with power-down controlled by the chip enable "CEB". When chip enable goes to high, SNR032 will entry power-down mode in order to save the power consumption.

BUS INTERFACE
SNR032 provides three different bus modes to connect to host CPU, AD-bus mode, byte mode and word mode. And the switching between different modes is depended on the pin option "TYPE" and "MODE". The following table is shown the relation ship of "TYPE", "MODE" pins and mode switching. Mode AD-Bus Interface Byte Mode Interface Word Mode Interface TYPE pin VDD GND GND MODE pin Don't care GND VDD
4.1 AD-Bus Interface For 8-bit AD (address/data) bus interface, all the address and data communication between SNC710 and SNR032 are through data bus D[0..7]. SNC710 allows user to connect maximum 2 external mask ROM. The option pin "TYPE" must connected to VDD then the AD-bus interface to be enable. In AD-Bus mode, SNR032 has three bank select pins BS2~BS4 to specify the memory region of SNR032. The address region setting of SNR032 is shown as bellow.
BS4~BS2 001 010 011 100 101 110 111 Address Region 0x0200000 ~ 0x03FFFFF 0x0400000 ~ 0x05FFFFF 0x0600000 ~ 0x07FFFFF 0x0800000 ~ 0x09FFFFF 0x0A00000 ~ 0x0BFFFFF 0x0C00000 ~ 0x0DFFFFF 0x0E00000 ~ 0x0FFFFFF
Table-1
Note: For the address region 0x00000~0x01FFFFF are reserved, so the setting of bank select pins BS4~BS2 CAN'T be the range 0000~0x0011.
