This document describes the features and characteristics of Taiwan Memory Technology Inc.'s T15V256A low power CMOS static RAM product, including high speed access time, low power consumption, and fully static operation.
The T15V256A is a low‑power, low‑voltage CMOS static RAM organized as 32,768 × 8 bits. It operates from a 2.7 V to 3.6 V supply and retains data down to 1.5 V. The device is offered in standard 28‑pin SOP and TSOP‑I (forward and reverse) packages.
Key features include high‑speed access times (50 ns to 100 ns), a maximum operating current of 35 mA, standby current of only 5 µA, and an operating temperature range from –40 °C to +85 °C. Detailed DC, AC, and timing characteristics are provided for design integration.
