M28C16B and M28C17B are low power, parallel EEPROM products with features such as fast access time, single voltage supply, and software data protection.
The M28C16B and M28C17B devices are 16‑Kbit (2K × 8) parallel EEPROMs fabricated with STMicroelectronics' single polysilicon CMOS technology. They operate from a single supply voltage (4.5 V‑5.5 V for M28CxxB, 2.7 V‑3.6 V for M28CxxB‑W) and provide a fast 90 ns access time at 5 V.
Key features include a 64‑byte page‑write capability, software data protection using the JEDEC algorithm, and robust endurance of at least 100 k erase/write cycles with a data retention of 40 years. The devices offer multiple status bits (DQ7, DQ6, DQ5) for write monitoring and are supplied in a PLCC‑32 package.
