Using LPC802 as I²C-busEEPROM
●LPC802 is a new member of the LPC800 series, which satisfies the demand for improved power efficiency. It is an ideal product for migration of market from 8-bit architecture with a very low cost. LPC802 has up to 15 MHz Cortex-M0 + core with 16 kB flash and 2 kB RAM. It is suitable for I/O expander and small programmable logic unit This application note discusses about LPC802 as an EEPROM like device. As LPC802 internal flash can endure at least 200k R/W cycles, it is ideal to use internal flash of LPC802 as non-volatile memory for EEPROM. With a dedicated firmware, LPC802 can transform into smart EEPROM with selectable interface such as, UART or SPI.
●This application note uses the I2C-bus interface of LPC802 and on-chip flash memory to simulate traditional I2C-bus EEPROM devices. It has the following information:
■General description, memory resources and layout, available peripherals
■Usage of flash IAP with example code
■Usage of I²C-bus module, especially for I²C-bus slave mode
