Applications
The M93C86-WDW6P is used in embedded systems requiring small-footprint non-volatile storage for configuration data, calibration coefficients, and user settings accessed via a 3-wire Microwire serial interface. Its 16 Kbit capacity in an 8-pin TSSOP suits applications such as automotive body-control modules, smart meters, industrial sensors, and consumer appliances that need frequent parameter updates within the 1,000,000 write-cycle lifetime. The selectable 8-bit or 16-bit memory width via the ORG pin provides flexibility for both byte-oriented and word-oriented microcontroller architectures.

Frequently Asked Questions
How many write/erase cycles does M93C86-WDW6P support, and how long will stored data last?
The M93C86-WDW6P is rated for 1,000,000 write/erase cycles per memory location and guarantees a minimum data retention of 40 years. This combination of high endurance and long retention makes it suitable for applications with frequent parameter updates, such as odometer or meter registers that write multiple times per day over the product lifetime.
What is the maximum clock frequency for the Microwire interface on M93C86-WDW6P?
The M93C86-WDW6P supports a maximum Microwire clock frequency of 2 MHz at the full supply voltage range. With a 200 ns access time, a complete 16-bit word read requires under 10 µs at 2 MHz, enabling fast configuration reads at system startup or during calibration routines in microcontroller-based designs.
How does M93C86-WDW6P's selectable memory width benefit different microcontroller architectures?
The M93C86-WDW6P supports both 8-bit and 16-bit memory width modes selected by the ORG pin logic level. In 16-bit mode the device contains 1024 x 16-bit words; in 8-bit mode it presents 2048 x 8-bit bytes. This flexibility allows the same hardware footprint to interface with 8-bit MCUs that handle byte-aligned data and 16-bit DSPs that prefer word-aligned transfers without any additional glue logic.
Is M93C86-WDW6P a suitable EEPROM for an automotive body-control module requiring long-term calibration storage?
Yes, the M93C86-WDW6P is well-matched to automotive body-control modules. Its 40-year data retention exceeds the typical 15-year vehicle lifetime, and its 1,000,000 write cycles accommodate daily calibration updates over the vehicle's service life. The 8-pin TSSOP package fits the space-constrained PCBs inside door modules and instrument clusters, and the e4 RoHS-compliant finish meets automotive environmental requirements.
