The MicroBolt is an industrial-oriented controller designed around NXP LPC2106 ARM7, 32-bit, 60 MHz, 53 Million Instructions Per Second microcontroller. It incorporates 19 digital inputs/outputs, a real-time clock, a serial boot loader, 128K Bytes of Flash and 64K Bytes of SRAM. MicroBolt is less than a cubic inch and consumes roughly 200 mW.
The MicroBolt utilizes a pair of UARTs to allow serial communication. With a 14.7456 MHz-system clock, the MicroBolt has the ability to communicate serially at baud rates up to 250Kbps. Very beneficial when time is a factor. SPI and I2C communications are also available.

The MicroBolt has 19 bi-directional bit-programmable, digital I/O lines capable of sinking/sourcing 4mA. Other peripheral features include a 32-bit PWM, a programmable watchdog timer, two 32-bit timers and an optional JTAG debugger connector.

Programs for the MicroBolt can be created in assembly or C programming languages. The MicroBolt is pin compatible with the Parallax Inc's BASIC STAMP.

Application Notes

The MicroBolt Development Board takes the MicroBolt I/O pins and expands them out to solder pads and headers for ease of connection when developing. It also connects UART0 and UART1 via jumpers to RS-232 drivers. The RS-232 drivers are connected to two DB9 connectors. UART1 can also be connected to a RS-485 driver for networking. The MicroBolt Development board provides connections to a LCD, SPI 12-bit 2 Channel ADC, LEDs, and an I2C EEPROM. This board also includes a prototyping area so the user can add on external circuitry. There is an onboard voltage regulator for powering the MicroBolt and additional circuitry. The MicroBolt development system comes complete with a MicroBolt, a MicroBolt Development Board, and a power supply.
