Memory IC datasheet and documents for 25C320-E/SN

25C320-E/SN

Memory IC Overview

The Microchip Technology 25C320-E/SN is a 32 Kbit (4096 x 8 bit) serial Electrically Erasable PROM. It utilizes an SPI-compatible interface with a maximum clock frequency of 3 MHz and operates within a voltage range of 4.5V to 5.5V. The device supports industrial temperature ranges from -40°C to +85°C and automotive ranges up to +125°C. Key electrical characteristics include a typical standby current of 500 nA, read current of 500 μA, and write current of 3 mA maximum. It features self-timed erase/write cycles with a maximum duration of 5 ms.

Memory IC Feature Summary

Supports block write protection for none, 1/4, 1/2, or all array segments via status register configuration.
Includes built-in power-on/off data protection circuitry and a write enable latch mechanism.
Provides hardware write protection through the WP pin in conjunction with the WPEN bit.
Allows serial communication pausing via the HOLD pin without resetting the sequence.

Memory IC Applications

Phones and handsets
Microcontroller systems requiring non-volatile storage
Industrial control applications

Memory IC Procurement Notes

Verify that the specific suffix 'E' corresponds to the required automotive temperature grade (+125°C max) and that the '/SN' designation matches the SOIC-8 package requirement. Confirm the voltage supply constraints align with the 4.5V to 5.5V operational range specified for the 25C320 series before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a 32 Kbit EEPROM with high-speed 3 MHz SPI operation is required. Ensure the system voltage remains strictly between 4.5V and 5.5V, as lower voltages are not supported by this specific variant. Consider the automotive temperature rating if the application environment exceeds standard industrial limits.

Memory IC Part Context

This part belongs to the 25XX320 family, which also includes the 25AA320 and 25LC320 variants. These devices share identical functional architectures but differ in operating voltage and speed specifications. The datasheet notes that this specific generation is not recommended for new designs, suggesting consideration of newer A-series alternatives.
