This is a 16/32-bit core in a 64-LQFP package, aimed at industrial control, sensor fusion, and serial-communication nodes where the ARM7 balance of code density and throughput still fits — think PLC I/O modules, motor-drive comms boards, or panel-mounted HMI backplanes. The 47 GPIO lines and the I²C, SPI, SSP, and UART/USART interfaces give it enough connectivity to handle a mixed-sensor array or a Modbus gateway without external muxing. ## On-chip data converters and peripherals Eight 10-bit ADC channels and one 10-bit DAC are integrated, enough for basic analog sensing — reading a potentiometer, a temperature sensor, or a current shunt — without an external converter. The Flash program memory is field-reprogrammable, so firmware updates are possible in-system via the UART or SPI bootloader.","metaTitle":"NXP LPC2138FBD640115 ARM7 MCU, 60MHz, 512KB Flash, 64-LQFP","metaDescription":"NXP LPC2138FBD640115 ARM7TDMI-S microcontroller, 60MHz, 512KB Flash, 32KB RAM, 47 GPIO, -40°C to 85°C, 64-LQFP.
