LPC2114FBD64: Single-chip 16/32-bit microcontrollers; 128/256 kB ISP/IAP flash with 10-bit ADC
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.

2.1 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.
- 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 µs.
- Two 32-bit timers (with four capture and four compare channels), PWM unit (six outputs), Real-Time Clock (RTC) and watchdog.
- Multiple serial interfaces including two UARTs (16C550), Fast I²C-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 µs.
- Vectored Interrupt Controller with configurable priorities and vector addresses.
- Up to forty-six 5 V tolerant general purpose I/O pins. Up to nine edge or level sensitive external interrupt pins available.
- 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 %) with 5 V tolerant I/O pads. 16/32-bit ARM7TDMI-S processor.
