The LPC2138FBD64/01 is a 16-/32-bit Microcontroller based on ARM7TDMI-S CPU with real-time emulation and embedded trace support. A 128-bit wide memory interface and an 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. The device incorporates 512kB embedded high speed flash, 32kB on-chip SRAM, 16-channel 10-bit A/D converter, 10-bit D/A converter, three 32-bit timers, PWM channels and 47 general-purpose I/O pins.
- In-system programming/In-application programming (ISP/IAP)
- EmbeddedICE RT and embedded trace interfaces
- Two 32-bit Timers/external event counters, PWM unit and watchdog
- Low power real-time clock with independent power and dedicated 32kHz clock input
- Multiple serial interfaces including two UARTs (16C550), two Fast I2C-bus (400 Kbit/s), SPI and SSP
- Vectored interrupt controller with configurable priorities and vector addresses
- Up to forty-seven 5V tolerant general purpose I/O pins
- Up to nine edge or level sensitive external interrupt pins available
- 60MHz Maximum CPU clock available from programmable on-chip PLL
- On-chip integrated oscillator operates with external crystal in range of 1MHz to 30MHz
- External oscillator up to 50MHz
- Power saving modes include Idle and power-down
- Individual enable/disable of peripheral functions as well as peripheral clock scaling down
- Processor wake-up from Power-down mode via external interrupt or BOD
- Single power supply chip with POR and BOD circuits
- Fast GPIO ports enable port pin toggling up to 3.5 times faster than the original LPC213x
- Dedicated result registers for ADC(s) reduce interrupt overhead
- UART0/1 include fractional baud rate generator, auto-bauding capabilities & handshake flow-control
- Additional BOD control enables further reduction of power consumption
