Data Sheet

LPC2104/2105/2106

GENERAL DESCRIPTION

The LPC 2104, 2105 and 2106 consist of an ARM7TDMI-S CPU with emulation support, the ARM7 Local Bus for interface to on-

chip memory controllers, the AMBA Advanced High-performance Bus (AHB) for interface to the interrupt controller, and the VLSI

Peripheral Bus (VPB, a compatible superset of ARM’s AMBA Advanced Peripheral Bus) for connection to on-chip peripheral

functions.

Features

• ARM7TDMI-S processor.

• 128 kilobyte on-chip Flash Program Memory with In-System Programming (ISP) and In-Application Programming (IAP)

capability. Flash programming time is 1 ms for up to a 512 byte line. Sector erase or chip erase is done in 400 ms.

• Up to 64 kilobyte Static RAM.

• Vectored Interrupt Controller.

• Emulation Trace Module supports real-time trace.

• Standard ARM Test/Debug interface for compatibility with existing tools.

• Two UARTs, one with full modem interface.

• Fast I2C serial interface (400kb/s).

• SPI serial interface.

• Two timers, each with 4 capture/compare channels.

• PWM unit with up to 6 PWM outputs.

• Real Time Clock.

• Watchdog Timer.

• General purpose I/O pins.

• CPU operating range up to 60 MHz.

• Dual power supply.

- CPU operating voltage range of 1.65V to 1.95V (1.8V +/- 8.3%).

- I/O power supply range of 3.0V to 3.6V (3.3V +/- 10%).

• Two low power modes, Idle and Power Down.

• Processor wakeup from Power Down mode via external interrupt.

• Individual enable/disable of peripheral functions for power optimization.

• On-chip crystal oscillator with an operating range of 10 MHz to 25 MHz.

• On-chip PLL allows CPU operation up to the maximum CPU rate. May be used over the entire crystal operating range.
