Somehow I’ve been sticked to NXP LPC2xxx series microcontrollers and left other brands behind. There are many major manufacturers of ARM based single board computers. One of them (EMBLITZ) that is worth to pay attention is NXP with its lpc2129 (ARM7)
- Processor: LPC2129
- 2x serial ports (one for ISP and the other for serial communication)
- 2xCAN ports with complete physical layer implementation on board via drivers(MCP2551)
- JTAG Connector header box in 2x10 pin layout provides ARM-JTAG Interface compatibility
- 12.00 MHz Crystal
- RESET button
- RESET circuit can be also controlled externally by Philips ISP utility via RS232
- Dual Power supply (either through USB or using external power adapter).
- Eight status LEDs with buffers and chip select
- Four buttons Potentiometer connected to analog input AIN0
- BSL jumper for boot loader enable
- DBG jumper for JTAG enable
- JRST jumper to enable external RESET control by RS232
- One Seven Segment Display with shift register and chip select
- Single power supply: 7V to 9V DC or can be connected to the USB port of the computer
- Power supply status LED
- Three on-board voltage regulators 1.8V, 3.3V and 5V with up to 800mA current
- Extension headers for all µC ports
- On board prototyping area
- 16/32-bit ARM7TDMI-S microcontroller.
- 16 kB on-chip RAM,256 kB Flash Program Memory supports upto 60 MHz frequency.
- In-System Programming (ISP) and In-Application Programming (IAP) via on-chip boot-loader software.
- On-chip Embedded-ICE-RT, Embedded Trace Macrocell debugger.
- Two interconnected CAN interfaces with advanced acceptance filters.
- Four channel 10-bit A/D converter with conversion time as low as 2.44 ms.
- Multiple serial interfaces including two UARTs (16C550).
- Fast I2C (400 kbits/s) and two SPIs.
- Phase-Locked Loop with settling time of 100 ms.
- Vectored Interrupt Controller with configurable priorities and vector addresses.
- Two 32-bit timers (with four capture and four compare channels), PWM unit (six outputs), Real Time Clock and Watchdog.
- Up to forty-six 5V 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.
- PU operating voltage range of 1.65V to 1.95V
(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.
