LPC11D14FBD100/302

Description

The LPC11D14 is a ARM Cortex-M0 based, low-cost 32-bit MCU family, designed for 8/16-bit microcontroller applications, offering performance, low power, simple instruction set and memory addressing together with reduced code size compared to existing 8/16-bit architectures. The LPC11D14 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.
