LPC2292/2294 16/32-bit ARM microcontrollers 256 kB ISP/IAP flash with CAN, 10-bit ADC and external memory interface Rev. 8 8 June 2011 Product data sheet 1. General description The LPC2292/2294 microcontrollers are based on a 16/32-bit ARM7TDMI-S CPU with real-time emulation and embedded trace support, together with 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 the 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, 2/4 (LPC2294) advanced CAN channels, PWM channels and up to nine external interrupt pins these microcontrollers are particularly suitable for automotive and industrial control applications as well as medical systems and fault-tolerant maintenance buses. The number of available GPIOs ranges from 76 (with external memory) through 112 (single-chip). With a wide range of additional serial communications interfaces, they are also suited for communication gateways and protocol converters as well as many other general-purpose applications. Remark: Throughout the data sheet, the term LPC2292/2294 will apply to devices with and without the /00 or /01 suffix. The suffixes /00 and /01 will be used to differentiate from other devices only when necessary. 2. Features and benefits 2.1 Key features brought by LPC2292/2294/01 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 LPC2292/2294/00 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.LPC2292/2294 NXP Semiconductors 16/32-bit ARM microcontrollers with external memory interface 16 kB on-chip static RAM and 256 kB on-chip flash program memory. 128-bit wide interface/accelerator enables high-speed 60 MHz operation.
