LPC2104/2105/2106

General description

The UART are based on a 16/32-bit ARM7TDMI-S CPU with real-time emulation and embedded trace support, together with 128 kB of embedded high speed flash memory. A 128-bit wide 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 pct with minimal performance penalty.

Due to their tiny size and low power consumption, these microcontrollers are ideal for applications where miniaturization is a key requirement, such as access control and point-of-sale. With a wide range of serial communications interfaces and on-chip SRAM options up to 64 kB, they are very well suited for communication gateways and protocol converters, soft modems, voice recognition and low end imaging, providing both large buffer size and high processing power. Various 32-bit timers, PWM channels, and 32 GPIO lines make these microcontrollers particularly suitable for industrial control and medical systems.

Remark: Throughout the data sheet, the term LPC2104/2105/2106 will apply to devices with and without /00 and /01 suffixes. Suffixes will be used to differentiate devices whenever they include new features.

Features

New features implemented in LPC2104/2105/2106/01 devices

• Fast GPIO port enables port pin toggling up to 3.5 times faster than the original device and also allows for a port pin to be read at any time regardless of its function.
• UART 0/1 include fractional baud rate generator, autobauding capabilities, and handshake flow-control fully implemented in hardware.
• Buffered SSP serial controller supporting SPI, 4-wire SSI, and Microwire formats.
• SPI programmable data length and master mode enhancement.
• Diversified Code Read Protection (CRP) enables different security levels to be implemented.
• General purpose timers can operate as external event counters.

Key common features

• 16/32-bit ARM7TDMI-S processor.
• 16/32/64 kB on-chip static RAM.
• 128 kB on-chip flash program memory. 128-bit-wide interface/accelerator enables high speed 60 MHz operation.
• In-System Programming (ISP) and In-Application Programming (IAP) via on-chip bootloader software. Flash programming takes 1 ms per 512 B line. Single sector or full chip erase takes 400 ms.
• Vectored Interrupt Controller with configurable priorities and vector addresses.
• 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.
• Multiple serial interfaces including two UARTs (16C550), Fast I²C-bus (400 kbit/s), and SPI.
• Two 32-bit timers (7 capture/compare channels), PWM unit (6 outputs), Real Time Clock and Watchdog.
• Up to thirty-two 5 V tolerant general purpose I/O pins in a tiny LQFP48 (7 mm x 7 mm) package.
• 60 MHz maximum CPU clock available from programmable on-chip Phase-Locked Loop with settling time of 100 us.
• The on-chip crystal oscillator should have an operating range of 1 MHz to 25 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 1.65 V to 1.95 V (1.8 V +- 8.3 pct).
  • I/O power supply range of 3.0 V to 3.6 V (3.3 V +- 10 pct) with 5 V tolerant I/O pads.
