LPC2114/2124 Single-chip 16/32-bit microcontrollers 128/256 kB ISP/IAP flash with 10-bit ADC Rev. 7 10 June 2011 Product data sheet 1. General description The LPC2114/2124 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 compact 64-pin package, low power consumption, various 32-bit timers, 4-channel 10-bit ADC, PWM channels and 46 fast GPIO lines with up to nine external interrupt pins these microcontrollers are particularly suitable for industrial control, medical systems, access control and point-of-sale. 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 LPC2114/2124 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 LPC2114/2124/01 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 LPC2114/2124/00 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 tiny LQFP64 package. 16 kB on-chip static RAM.LPC2114/2124 NXP Semiconductors Single-chip 16/32-bit microcontrollers 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 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 (ETM) enables non-intrusive high speed real-time tracing of instruction execution. Four-channel 10-bit ADC with conversion time as low as 2.44 s. Two 32-bit timers (with four capture and four compare channels), PWM unit (six outputs), Real-Time Clock (RTC) and watchdog. 2 Multiple serial interfaces including two UARTs (16C550), Fast I C-bus (400 kbit/s) and two SPIs. 60 MHz maximum CPU clock available from programmable on-chip Phase-Locked Loop with settling time of 100 s.
