This document introduces the features and characteristics of M93S66, M93S56 M93S46 4Kbit, 2Kbit and 1Kbit (16-bit wide) MICROWIRE Serial Access EEPROM with Block Protection
This document provides detailed specifications for a range of 4K, 2K, and 1K bit serial Electrically Erasable Programmable Memory (EEPROM) products, collectively referred to as M93Sx6. The devices utilize the Industry Standard MICROWIRE Bus and support single supply voltages ranging from 1.8V to 5.5V depending on the specific model variant.
Key features include self-timed programming cycles with auto-erase, user-defined write-protected areas managed by a Protection Register, and page write modes. The datasheet details instruction sets for reading, writing, and protection management, along with absolute maximum ratings, DC and AC electrical characteristics, and mechanical package data for PDIP, SO, and TSSOP formats.
