LPC4357FET256K

The LPC4357FET256K from NXP Semiconductors is an ARM Cortex-M4 based microcontroller with an integrated ARM Cortex-M0 coprocessor, designed for embedded applications. It operates at CPU frequencies of up to 204 MHz and includes a hardware floating-point unit (FPU).

Key features include up to 1 MB of on-chip flash memory and 136 kB of on-chip SRAM, along with 16 kB of EEPROM memory. The microcontroller is equipped with two high-speed USB controllers, Ethernet, an LCD interface, and an external memory controller. Advanced configurable peripherals such as the State Configurable Timer (SCTimer/PWM) and the Serial General Purpose I/O (SGPIO) interface are also included, alongside multiple digital and analog peripherals.

This device is housed in a 256-LBGA (17x17) package and supports surface mount installation. It operates within a voltage range of 2.4V to 3.6V and has an operating temperature range of -40°C to 85°C (TA). Connectivity options include CANbus, Ethernet, I2C, SPI, UART/USART, and USB, making it suitable for a wide array of embedded systems.

The ARM Cortex-M4 core provides system enhancements like low power consumption and enhanced debug features, supporting single-cycle digital signal processing and SIMD instructions. The Cortex-M0 coprocessor is designed for energy efficiency and can off-load control or peripheral handling tasks from the main M4 processor.
