AS7C256A-15TCN Description

Short technical summary and product information.

The AS7C256A-15TCN is a high-performance 256Kbit CMOS Static Random-Access Memory (SRAM) device organized as 32,768 words by 8 bits. It offers a fast address access time of 15 ns and an output enable access time of 7 ns, making it suitable for applications requiring quick data retrieval.

 

This SRAM operates within a voltage range of 4.5V to 5.5V and consumes very low power in standby mode (11 mW max). It is designed for easy memory expansion using Chip Enable (CE) and Output Enable (OE) inputs. The device features TTL-compatible, three-state I/O and is available in a 28-pin TSOP I package for surface mounting.

 

Key electrical characteristics include a write cycle time of 15 ns and a maximum operating current of 65 mA. The device also supports 2.0V data retention and has ESD protection exceeding 2000 volts.
