V53C8125H40中文资料茂矽电子数据手册PDF规格书

Description

The V53C8125H is a high speed 131,072 x 8 bit CMOS dynamic random access memory. The V53C8125H offers a combination of features: Fast Page Mode for high data bandwidth, fast usable speed, CMOS standby current.

All inputs and outputs are TTL compatible. Input and output capacitances are significantly lowered to allow increased system performance. Fast Page Mode operation allows random access of up to 512 columns (x9) bits within a row with cycle times as short as 19 ns. Because of static circuitry, the CAS clock is not in the critical timing path. The flow through column address latches allow address pipelining while relaxing many critical system timing requirements for fast usable speed. These features make the V53C8125H ideally suited for graphics, digital signal processing and high performance peripherals.
