Key Features
- 16 Kbit MICROWIRE EEPROM with selectable 8-bit or 16-bit data width for flexible microcontroller compatibility
- 1 MHz maximum serial clock frequency enabling fast data access in automotive and industrial serial memory applications
- 1,000,000 write/erase cycle endurance and 40-year data retention in a compact SOIC-8 RoHS-compliant package
Applications
The M93C86-RDW6TP is commonly used in automotive body electronics, appliance controllers, and industrial equipment for storing configuration data, odometer values, immobilizer codes, and calibration parameters that must survive power loss. Its MICROWIRE 3-wire serial interface at up to 1 MHz integrates easily with legacy automotive MCUs and 8-bit microcontrollers that support SPI or dedicated MICROWIRE peripherals. The selectable 8-bit or 16-bit word organization and SOIC-8 package make it a drop-in replacement for common automotive EEPROM applications requiring up to 16 Kbits of non-volatile storage.

Frequently Asked Questions
What memory capacity and word width options does the M93C86-RDW6TP provide?
The M93C86-RDW6TP stores 16 Kbits (2 Kbytes) of data and supports selectable word widths of either 8 bits or 16 bits, configurable via an external organization select pin. In 16-bit mode the device contains 1024 words of 16 bits each, while in 8-bit mode it provides 2048 words of 8 bits, giving designers flexibility to match the native data bus width of the host microcontroller.
What serial interface does the M93C86-RDW6TP use and how fast is the maximum clock?
The M93C86-RDW6TP uses the MICROWIRE 3-wire serial interface (clock, data-in, data-out, chip-select) with a maximum clock frequency of 1 MHz. This protocol is compatible with most SPI-capable microcontrollers operating in SPI Mode 0 or Mode 3, allowing firmware-level compatibility with standard SPI driver libraries and requiring minimal porting effort when migrating from SPI EEPROM devices.
How does the M93C86-RDW6TP write endurance and data retention compare to competing serial EEPROMs?
The M93C86-RDW6TP guarantees 1,000,000 write/erase cycles per cell and a minimum data retention of 40 years, which is comparable to Microchip 93C86 and Atmel AT93C86 devices in the same MICROWIRE EEPROM segment. For automotive applications requiring AEC-Q100 qualification with extended temperature ranges of -40°C to +125°C, designers should verify the specific temperature grade suffix on the ordered part number to confirm automotive-grade compliance.
In which automotive and industrial applications is the M93C86-RDW6TP most commonly deployed?
The M93C86-RDW6TP is widely deployed in automotive instrument clusters for storing odometer readings and trip data, in immobilizer and key-fob systems for transponder codes, and in industrial motor drives for storing run-hour counters and fault logs. Its 16 Kbit capacity accommodates these use cases within a single SOIC-8 device, and the MICROWIRE interface's 1 MHz speed allows full 2 Kbyte reads in under 2 ms, which is fast enough for ignition-cycle initialization in body control modules.
