LPC2212/2214 Single-chip 16/32-bit ARM microcontrollers 128/256 kB ISP/IAP flash with 10-bit ADC and external memory interface Rev. 5 14 June 2011 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 and benefits 2.1 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. 2.2 Key features common for all devices 16/32-bit ARM7TDMI-S microcontroller in a LQFP144 package.LPC2212/2214 NXP Semiconductors Single-chip 16/32-bit ARM microcontrollers 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.
