Product details
Overview
93C06E/SN from Microchip Technology is a 256-bit (128-word × 2-bit) serial EEPROM with Microwire-compatible 3-wire interface, 1.8–5.5 V supply range, and 100-year data retention. It operates up to 3 MHz clock rate and supports both ORG pin-selectable 128×2 or 64×4 organization. Used in industrial control panels for calibration storage and parameter backup.
For engineers reviewing the 93C06E/SN datasheet, 93C06E/SN pinout, 93C06E/SN application, or 93C06E/SN equivalent, key selection factors include Microwire protocol compliance, dual-organization flexibility via ORG pin, guaranteed 1M endurance cycles, and extended temperature operation (–40°C to +85°C).
Technical Context
This device implements a synchronous serial interface using CS, SK, and DI pins for command and data input, and DO for serial output. Internal address counter auto-increments during sequential read/write operations, and write cycle completion is verified by polling the BUSY bit.
It features hardware write protection via WP pin and software-controlled write enable/disable (WREN/WRDI), with erase-before-write architecture ensuring data integrity. The ORG pin determines memory mapping at power-up and remains latched until next reset.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| WP | Write Protect | Hardware lock: low = write enabled; high = all write/erase commands inhibited |
| VCC | Power Supply | Positive supply rail (1.8–5.5 V); decoupling capacitor required near pin |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT93C46D-SSH-T | Same 256-bit capacity and Microwire interface, but fixed 64×4 organization (no ORG pin) | Lacks dual-organization flexibility; requires firmware alignment to 4-bit word access | Choose when memory width is fixed and board space favors smaller 8-lead TSSOP |
| STK11C68-MF1 | 1K-bit capacity, same SOIC-8 package, but uses SPI interface instead of Microwire | Requires different driver stack and clock polarity/phase handling | Choose only if migrating to SPI-based host and additional memory depth is needed |
Compared with AT93C46D-SSH-T and STK11C68-MF1, the 93C06E/SN uniquely supports runtime organization switching via ORG pin, maintains strict Microwire timing compatibility, and delivers guaranteed 100-year retention at full industrial temperature range - critical for calibration-critical systems.

FAQ
What is the maximum clock frequency supported by the 93C06E/SN?
The 93C06E/SN supports a maximum serial clock (SK) frequency of 3 MHz across its full operating voltage and temperature range. This timing specification is tested and guaranteed per Microchip's MCHPS04459-1 datasheet, enabling reliable high-speed parameter reads in time-constrained embedded systems without requiring clock stretching or wait states. The 93C06E/SN maintains this performance from 1.8 V to 5.5 V supply.
How does the ORG pin affect memory organization in the 93C06E/SN?
The ORG pin on the 93C06E/SN selects between two memory configurations at power-up: logic low (VSS) configures 128 words × 2 bits, while logic high (VCC) configures 64 words × 4 bits. This setting is latched internally and remains active until the next power cycle. The 93C06E/SN does not support dynamic reconfiguration - the ORG state must be fixed during PCB design.
Does the 93C06E/SN require an external pull-up resistor on the DO pin?
No, the 93C06E/SN features an internally weak-pullup on the DO pin, eliminating the need for an external resistor. During read operations with CS low, DO actively drives data; when CS is high, DO enters high-impedance state. This internal design simplifies board layout and reduces BOM count while maintaining signal integrity in noise-sensitive environments per the 93C06E/SN datasheet specifications.
What write protection mechanisms are implemented in the 93C06E/SN?
The 93C06E/SN implements dual-layer write protection: hardware-level inhibition via the WP pin (high = write disabled), and software-level control through WREN/WRDI commands. Both must be satisfied for a write or erase operation to execute. This architecture prevents accidental overwrites during power transitions or firmware faults, and is fully documented in the 93C06E/SN datasheet revision associated with MCHPS04459-1.
Is the 93C06E/SN compatible with standard Microwire controllers?
Yes, the 93C06E/SN is fully compliant with the Microwire protocol as defined by National Semiconductor and supported by Microchip's legacy controller peripherals. It accepts standard 9-bit command words (including EWEN, ERAL, WRAL, READ), supports address auto-increment, and observes correct timing margins for setup/hold on DI and DO relative to SK. Host firmware written for other Microwire EEPROMs can typically interface with the 93C06E/SN with minimal adaptation.
