LPC2157
description
The LPC2157/2158 is a multi-chip module consisting of a LPC2138/2148 single-chip microcontroller bined with a PCF8576D Universal LCD driver in a low-cost 100-pin package. The LCD driver provides 32 segments and supports from 1 to 4 backplanes. Display overhead is minimized by an on-chip display RAM with auto-increment addressing. Refer to the respective LPC2148 and LPC2138 user manual for details.
2. Features
I 128-bit wide interface/accelerator enables high-speed 60 MHz operation. N 32 k B to 40 k B of on-chip static RAM and 512 k B of on-chip flash memory. I USB 2.0 Full-speed pliant device controller with 2 k B of endpoint RAM. N An additional 8 k B of on-chip RAM accessible to USB by DMA (LPC2158 only). I 32 segment × 4 backplane LCD controller supports from 1 to 4 backplanes. I Single 10-bit DAC provides variable analog output. I Low power Real-Time Clock (RTC) with independent power and 32 k Hz clock input. I Multiple serial interfaces including two UARTs (16C550), two...
