RC28F256K3C120 RC28F256K3C120 Intel 256Kb flash memory, 32K x 8 CMOS flash
The RC28F256K3C120 is a high-reliability 256Kb (32K x 8) CMOS flash memory chip manufactured by Intel (formerly under Numonyx/Micron), designed for embedded systems, industrial controls, and automotive applications. This device operates at a wide voltage range of 2.7V to 3.6V, ensuring compatibility with low-power and battery-powered systems, while delivering fast access times of 120ns for efficient data retrieval. It features a flexible block architecture with 16 uniform 4K-byte sectors, allowing for individual erase and programming operations, which is ideal for firmware storage, configuration data, and boot code applications. The chip supports JEDEC-standard commands and integrates a write protection mechanism to prevent accidental data corruption.
A key strength of the RC28F256K3C120 is its high endurance and long-term data retention, supporting 100,000 program/erase cycles per sector and 20 years of data retention, making it suitable for mission-critical applications. The device includes an asynchronous interface for easy integration with 8-bit microcontrollers and legacy systems, along with hardware and software write protection to enhance system security. It also features a low-power standby mode, consuming minimal current when inactive, which is beneficial for energy-efficient designs. The chip is available in a 32-pin PLCC (Plastic Leaded Chip Carrier) package, ensuring robust mechanical stability in industrial and automotive environments.
The RC28F256K3C120 is designed for harsh operating conditions, with an extended temperature range of -40°C to +85°C, ensuring reliable performance in automotive, aerospace, and industrial automation systems. It is fully compatible with Intel’s flash memory ecosystem, supported by standard flash programming tools, and can be used as a drop-in replacement for older 28F series flash memories. Its low pin-count interface simplifies PCB design, while its high-speed read and byte-programming capabilities make it a versatile choice for real-time embedded applications.
