This is a preliminary document about A62S8308 series 256K x 8 bit low voltage CMOS SRAM. The product has a power supply range of 2.7V to 3.6V, access times of 55ns (max.) for VCC = 3.0V to 3.6V, 70ns (max.) for VCC = 2.7V to 3.6V, current of 40mA (max.) in operating mode, 10µA (max.) in standby mode, and an extended operating temperature range of -25°C to 85°C.
The A62S8308 series is a static random‑access memory organized as 262,144 words × 8 bits. It operates from a low supply voltage of 2.7 V to 3.6 V and features TTL‑compatible inputs and three‑state outputs for easy bus interfacing. The device requires no clock or refresh and includes two chip‑enable inputs and an output‑enable input for power‑down control.
Key specifications include a 55 ns maximum read access time at 3.0‑3.6 V (70 ns at 2.7‑3.6 V), 40 mA operating current, 10 µA standby current, and an operating temperature range of –25 °C to +85 °C. The SRAM is offered in 32‑pin SOP, TSOP, sTSOP, and 36‑ball Mini‑BGA (6 × 8) packages, with a data‑retention voltage as low as 2 V.
