AS7C3256A-8 is a 3.3V 32K X 8 CMOS SRAM (Common I/O) with high speed, low power consumption and easy expansion.
The AS7C3256A-8 SRAM is organized as 32,768 words by 8 bits and operates from a 3.3 V supply. It offers high‑speed performance with an 8 ns address access time and a 5 ns output‑enable access time, while consuming only 216 mW active power and 7.2 mW in standby. The device features TTL‑compatible three‑state I/O, ESD protection of 2000 V, and latch‑up current greater than 200 mA.
The memory is available in standard 28‑pin JEDEC packages: a 300 mil SOJ and an 8 × 13.4 mm TSOP. Recommended operating conditions include a supply voltage range of 3.0 V to 3.6 V (typical 3.3 V) and an ambient temperature range up to +125 °C. Ordering information and part‑number suffixes for lead‑free versions are provided in the document.
