1. INTRODUCTION
GENERAL DESCRIPTION
The LPC2119/2129/2194/2292/2294 are based on a 16/32 bit ARM7TDMI-S
trace support, together with 128/256 kilobytes (kB) of embedded high speed flash memory. A 128-bit wide internal memory
interface and a unique accelerator architecture enable 32-bit code execution at maximum clock rate. For critical code size
applications, the alternative 16-bit Thumb Mode reduces code by more than 30% with minimal performance penalty.
With their comapct 64 and 144 pin packages, low power consumption, various 32-bit timers, combination of 4-channel 10-bit ADC
and 2/4 advanced CAN channels or 8-channel 10-bit ADC and 2/4 advanced CAN channels (64 and 144 pin packages
respectively), and up to 9 external interrupt pins these microcontrollers are particularly suitable for industrial control, medical
systems, access control and point-of-sale.
Number of available GPIOs goes up to 46 in 64 pin package. In 144 pin packages number of available GPIOs tops 76 (with
external memory in use) through 112 (single-chip application). Being equipped wide range of serial communications interfaces,
they are also very well suited for communication gateways, protocol converters and embedded soft modems as well as many
other general-purpose applications.
FEATURES
• 16/32-bit ARM7TDMI-S microcontroller in a 64 or 144 pin package.
• 16 kB on-chip Static RAM
• 128/256 kB on-chip Flash Program Memory (at least 10,000 erate/write cycles over the whole temperature range). 128-bit wide
interface/accelerator enables high speed 60 MHz operation.
• External 8, 16 or 32-bit bus (144 pin package only)
• In-System Programming (ISP) and In-Application Programming (IAP) via on-chip boot-loader software. Flash programming
takes 1 ms per 512 byte line. Single sector or full chip erase takes 400 ms.
• EmbeddedICE-RT interface enables breakpoints and watch points. Interrupt service routines can continue to execute whilst
the foreground task is debugged with the on-chip RealMonitor software.
• Embedded Trace Macrocell enables non-intrusive high speed real-time tracing of instruction execution.
• Two/four interconnected CAN interfaces with advanced acceptance filters.
• Four/eight channel (64/144 pin package) 10-bit A/D converter with conversion time as low as 2.44 ms.
• Two 32-bit timers (with 4 capture and 4 compare channels), PWM unit (6 outputs), Real Time Clock and Watchdog.
• Multiple serial interfaces including two UARTs (16C550), Fast I
• 60 MHz maximum CPU clock available from programmable on-chip Phase-Locked Loop.
• Vectored Interrupt Controller with configurable priorities and vector addresses.
• Up to forty-six (64 pin) and hundred-twelve (144 pin package) 5 V tolerant general purpose I/O pins. Up to 12 independent
external interrupt pins available (EIN and CAP functions).
• On-chip crystal oscillator with an operating range of 1 MHz to 30 MHz.
• Two low power modes, Idle and Power-down.
• Processor wake-up from Power-down mode via external interrupt.
• Individual enable/disable of peripheral functions for power optimization.
• 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%).
