| Description | The AS4C64M16D2A-25BIN is a high-speed, 1-gigabit (Gb) DDR2 Synchronous Dynamic Random-Access Memory (SDRAM) from Alliance Memory, organized as 64 million words by 16 bits (64M x 16). Designed for high-performance applications, it features a double-data-rate architecture with an 8n prefetch, enabling data transfer rates up to 400 MHz. The device operates with a supply voltage range of 1.7V to 1.9V and supports fully synchronous operations with a differential clock (CK and CK#). It includes eight internal banks for concurrent operation and offers programmable CAS latencies of 3, 4, and 5. Additional features encompass bidirectional single/differential data strobes (DQS and DQS#), on-die termination (ODT), off-chip driver (OCD) impedance adjustment, and automatic self-refresh with a refresh period of 7.8 µs. The AS4C64M16D2A-25BIN is housed in an 84-ball FBGA package and operates within an industrial temperature range of -40°C to 95°C, making it suitable for various applications requiring reliable and efficient memory solutions.
