ARM7 MCU with integrated analog for industrial control
The NXP LPC2138FBD64/01EL is a 16/32-bit ARM7 microcontroller from the LPC2100 series, clocked at 60 MHz. It packs 512 KB of Flash and 32 KB of RAM, plus an 8-channel 10-bit ADC and a single 10-bit DAC, all in a 64-LQFP package.
60 MHz ARM7 core — throughput for control loops
The 60 MHz ARM7 core handles real-time control loops and protocol parsing without external clock management — the internal oscillator keeps the board simple.
Connectivity includes I²C, SPI, SSI, SSP, UART/USART, and Microwire — enough for daisy-chained ADCs, external EEPROM, and a serial debug console. The 47 general-purpose I/O lines cover panel buttons, LED indicators, and relay drivers.
