NXP | LPC2114FBD64/01,15

The LPC2114FBD64/01,15 is a 60 MHz 16/32-bit single-chip microcontroller with real-time emulation and embedded trace support.

The 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.

Features :

• 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.

• 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.
• 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 ms.
• 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 ms.
• Vectored Interrupt Controller with configurable priorities and vector addresses.
• 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.
