General description

The LPC2157/2158 is a multi-chip module consisting of a LPC2138/2148 single-chip

microcontroller combined 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.

Features

I 128-bit wide interface/accelerator enables high-speed 60 MHz operation.

N 32 kB to 40 kB of on-chip static RAM and 512 kB of on-chip ﬂash memory.

I USB 2.0 Full-speed compliant device controller with 2 kB of endpoint RAM.

N An additional 8 kB 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 kHz clock input.

I Multiple serial interfaces including two UARTs (16C550), two Fast I2C-bus (400 kbit/s),

SPI and SSP with buffering and variable data length capabilities.

I High-accuracy internal RC oscillator option allows operation without external oscillator

components. The RC oscillator option is selectable and ﬁne tunable.

I 2.4 V to 3.6 V VDD operating range. I/O pins are 5 V tolerant (may be pulled up or

driven to 5.5 V).

I 100-pin LQFP package with 38 microcontroller I/O pins minimum.

I Individual enable/disable of peripheral functions as well as peripheral clock scaling for

additional power optimization.
