25C320-I/P

The Microchip Technology 25C320-I/P is a 32 Kbit serial Electrically Erasable PROM (EEPROM) designed for efficient data storage. It utilizes a standard Serial Peripheral Interface (SPI) for communication, requiring clock (SCK), data in (SI), and data out (SO) lines, controlled by a Chip Select (CS) input. This device supports a voltage range of 4.5V to 5.5V and operates at a maximum clock frequency of 3 MHz.

Key features include a 4096 x 8 bit organization with a 32-byte page size and a write cycle time of 5 ms maximum. It offers low-power CMOS technology with a typical read current of 500 μA and a typical standby current of 500 nA. The EEPROM boasts high reliability with an endurance of 1M write/erase cycles and data retention exceeding 200 years. It also features built-in write protection mechanisms, including a write-protect pin and power-on/off data protection.

This EEPROM is available in an 8-Pin PDIP package, suitable for through-hole mounting. The operating temperature range is -40°C to +85°C, making it suitable for industrial applications. The device also supports block write protection, allowing for selective array protection.

Designed for various embedded applications, the 25C320-I/P provides reliable non-volatile data storage. Its SPI interface simplifies integration into microcontrollers and other digital systems. The robust design and features like self-timed erase and write cycles ensure dependable operation.
