Scalable Entry Level 32-bit Microcontroller (MCU) based on Arm® Cortex®-M0 Cores

The LPC11Dxx MCU family is an Arm^® Cortex^®-M0 based- low-cost 32-bit MCU operating at CPU frequencies of up to 50 MHz. The LPC11xx MCU is designed for 8/16-bit microcontroller operations, offering performance, low power, simple instruction set reduce code size compared to existing 8/16-bit architectures.

The LPC11Dxx is a dual-chip module consisting of a LPC1114 single-chip microcontroller combined with a PCF8576D Universal LCD driver in a low-cost 100-pin package. The LCD driver provides 40 segments and supports from one to four backplanes. Display overhead is minimized by an on-chip display RAM with auto-increment addressing.

The peripheral complement of the LPC11Dxx MCU includes 32KB of flash memory, 8 KB of SRAM, one fast-mode Plus I2C-bus interface, one RS-485/EIA-485 UART, up to two SPI interfaces with SSP features, four general purpose counters/timers, a 10-bit ADC, and up to 42 general purpose I/O pins.
