ARM7 MCU with integrated analog for mixed-signal control
The NXP LPC2136FBD64/01EL is a 16/32-bit microcontroller from the LPC2100 series, clocked at 60 MHz with 256 KB of Flash and 32 KB of SRAM. It has 47 I/O lines, a 16-channel 10-bit ADC, a 10-bit DAC, and serial interfaces including I²C, SPI, and UART.
256 KB of Flash is sized for mid-complexity firmware: a bootloader, a real-time kernel, communication stacks, and application code. The 32 KB SRAM splits between stack, heap, and data buffers.
