LPC2212/2214
16/32-bit ARM microcontrollers; 128/256 kB ISP/IAP flash with
10-bit ADC and external memory interface
Rev. 04 — 3 January 2008
Product data sheet
1. 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 % 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.
2. Features
2.1 Key features brought by LPC2212/2214/01 devices
I
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.
I
Dedicated result registers for ADC(s) reduce interrupt overhead. The ADC pads are
5 V tolerant when configured for digital I/O function(s).
I
UART0/1 include fractional baud rate generator, auto-bauding capabilities and
handshake flow-control fully implemented in hardware.
I
Buffered SSP serial controller supporting SPI, 4-wire SSI, and Microwire formats.
I
SPI programmable data length and master mode enhancement.
I
Diversified Code Read Protection (CRP) enables different security levels to be
implemented. This feature is available in LPC2212/2214/00 devices as well.
I
General purpose timers can operate as external event counters.
2.2 Key features common for all devices
