LPC2212/2214

General description

The LPC2212/2214 are based on a 16/32-bit ARM7TDMI-S CPU with real-time emulation and embedded trace support, together with 128/256 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.

With their 144-pin package, low power consumption, various 32-bit timers, 8-channel 10-bit ADC, PWM channels and up to nine external interrupt pins these microcontrollers are particularly suitable for industrial control, medical systems, access control and point-of-sale. Number of available fast GPIOs ranges from up to 76 pins (with external memory) through up to 112 pins (single-chip). With a 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.

Remark: Throughout the data sheet, the term LPC2212/2214 will apply to devices with and without the /00 or /01 suffixes. The /00 or the /01 suffix will be used to differentiate from other devices only when necessary.

Features

Key features brought by LPC2212/2214/01 devices

• Fast GPIO ports enable port pin toggling up to 3.5 times faster than the original device. They also allow for a port pin to be read at any time regardless of its function.
• Dedicated result registers for ADC(s) reduce interrupt overhead. The ADC pads are 5 V tolerant when configured for digital I/O function(s).
• UART0/1 include fractional baud rate generator, auto-bauding 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. This feature is available in LPC2212/2214/00 devices as well.
• General purpose timers can operate as external event counters.

Key features common for all devices

• 16/32-bit ARM7TDMI-S microcontroller in a LQFP144 package.
• 16 kB on-chip static RAM and 128/256 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.
• EmbeddedICE-RT and Embedded Trace interfaces offer real-time debugging with the on-chip RealMonitor software as well as high speed real-time tracing of instruction execution.
• Eight-channel 10-bit ADC with conversion time as low as 2.44 us.
• Two 32-bit timers (with four capture and four compare channels), PWM unit (six outputs), Real-Time Clock and Watchdog.
• Multiple serial interfaces including two UARTs (16C550), Fast I²C-bus (400 kbit/s) and two SPIs.
• Vectored Interrupt Controller with configurable priorities and vector addresses.
• Configurable external memory interface with up to four banks, each up to 16 MB and 8/16/32-bit data width.
• Up to 112 general purpose I/O pins (5 V tolerant). Up to nine edge or level sensitive external interrupt pins available.
• 60 MHz maximum CPU clock available from programmable on-chip Phase-Locked Loop with settling time of 100 ms.
• 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 1.65 V to 1.95 V (1.8 V +- 0.15 V).
  • 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.
