Description and Introduction

16Kbit, 8Kbit, 4Kbit, 2Kbit and 1Kbit (8-bit or 16-bit wide) MICROWIRE Serial Access EEPROM The M93C56-MN3T is a serial Electrically Erasable Programmable Read-Only Memory (EEPROM) manufactured by STMicroelectronics (STM). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Memory Size:** 16 Kbit (2 Kbyte) organized as 128 x 16-bit or 256 x 8-bit.
- **Interface:** Microwire (3-wire serial interface).
- **Supply Voltage:** 1.8V to 5.5V.
- **Operating Temperature Range:** -40°C to +85°C.
- **Write Time:** 5 ms (typical).
- **Endurance:** 4 million write cycles per byte.
- **Data Retention:** 200 years.
- **Package:** 8-lead SOIC (MN3T suffix).

### **Descriptions:**
- The M93C56-MN3T is a non-volatile memory device that supports both 8-bit and 16-bit organization modes.
- It features a sequential read operation for faster data access.
- The device includes a write enable latch and software data protection mechanisms to prevent accidental writes.
- It is compatible with industrial and automotive applications due to its wide voltage range and temperature tolerance.

### **Features:**
- **Serial Interface:** Uses clock (SK), data input (DI), and data output (DO) for communication.
- **Software Protection:** Write operations can be disabled via software commands.
- **Sequential Read Mode:** Allows continuous reading of memory locations.
- **Low Power Consumption:** Standby current as low as 5 µA (typical).
- **Self-Timed Programming Cycle:** No external timing components required.
- **Enhanced ESD Protection:** Protects against electrostatic discharge.

This information is based on the manufacturer's datasheet for the M93C56-MN3T EEPROM.
