SNR016
16M-bit Mask ROM
1. INTRODUCTION
The SNR016 is a signal power, 16M-bit, read only memory. It is organized as 2M bytes, operates for single 3V power supply, support static standby mode. The SNR016 embedded two different interfaces, one is a standard 8-bit interface bus which compatible with SNL310, another one is a special 8-bit AD (address/data) bus which compatible with SNC710. SNR016 offers automatic power-down, with power-down controlled by the chip enable "CEB". When chip enable goes to high, SNR016 will entry power-down mode in order to save the power consumption.
2. FEATURES
Power supply: 2.4V ~ 3.6V Memory Size: 16M-bit Totally static operation Embedded a standard 8-bit bus interface compatible with SNL310 or a 8-bit AD (address/data) bus interface compatible with SNC710 Access time: 200ns @3V

4. MEMORY MAPPING
For 8-bit AD (address/data) bus interface, all the address and data communication between SNC710 and SNR016 are through data bus D[0..7]. SNC710 allows user to connect maximum 2 external mask ROM, and SNR016 has 4 bank select pins (BS1~BS4) to specify the memory region of each mask ROM.
BS4~BS1 0010 0011 0100 0101 0110 0111 1000 1001 1010 1011 1100 1101 1110 1111 Address Region 0x0200000 ~ 0x02FFFFF 0x0300000 ~ 0x03FFFFF 0x0400000 ~ 0x04FFFFF 0x0500000 ~ 0x05FFFFF 0x0600000 ~ 0x06FFFFF 0x0700000 ~ 0x07FFFFF 0x0800000 ~ 0x08FFFFF 0x0900000 ~ 0x09FFFFF 0x0A00000 ~ 0x0AFFFFF 0x0B00000 ~ 0x0BFFFFF 0x0C00000 ~ 0x0CFFFFF 0x0D00000 ~ 0x0DFFFFF 0x0E00000 ~ 0x0EFFFFF 0x0F00000 ~ 0x0FFFFFF
Table-1 Note: For the address region 0x00000~0x01FFFFF are reserved, and the setting of bank select pins BS4~BS1 CAN'T be the range 0000~0x0001.
