A3V56S30FTP
A3V56S40FTP
256M Single Data Rate Synchronous DRAM
General Description
A3V56S30FTP is organized as 4-bank x 8,388,608-word x 8-bit Synchronous DRAM with LVTTL interface and
A3V56S40FTP is organized as 4-bank x 4,194,304-word x 16-bit. All inputs and outputs are referenced to the rising edge of
CLK. A3V56S30FTP and A3V56S40FTP achieve very high speed data rates up to 166MHz, and are suitable for main
memories or graphic memories in computer systems.
Features

- Maximum clock frequency :
- 6:166MHz<3-3-3>/-7:143MHz<3-3-3>/-75:133MHz<3-3-3>
- Fully synchronous operation referenced to clock rising edge
- 4-bank operation controlled by BA0, BA1 (Bank Address)
- /CAS latency- 2/3 (programmable)
- Burst length- 1/2/4/8/FP (programmable)
- Burst type- Sequential and interleave burst (programmable)
- Byte Control- DQM (A3V56S30FTP), DQML and DQMU (A3V56S40FTP)
- Random column access
- Auto precharge / All bank precharge controlled by A10
- Support concurrent auto-precharge
- Auto and self refresh
- 8192 refresh cycles /64ms
- LVTTL Interface
- Package
400-mil, 54-pin Thin Small Outline (TSOP II) with 0.8mm lead pitch
Pb-free package is available
