ARMite SBC from Coridium

Board maker Coridium Corp. is rolling out a very low-cost product called the ARMmite.

Priced at less than $50, ARMmite clocks a 60MHz ARM LPC2103 processor. Programmable in compiled BASIC, the ARMmite can churn through more than 10 million BASIC lines per second.

The LPC2103 is an ARM7TDMI-S-based 32bit RISC controller with Thumb extensions. It includes 10bit ADC, and accepts eight analog inputs. The device also packs two 32bit timers/external event counters, two 16bit timers/external event counters, a real-time clock with dedicated 32kHz clock input, and two 16C550-type UARTs.

Measuring 50-by-80mm, the ARMmite includes 24 digital I/O lines and an 8-channel ADC. The board provides 12Kbytes of code space, 5Kbtes for user data and 20Kbytes for system code.

I/O operations include PWM, SHIFTIN, SHIFTOUT, PULSIN, PULSOUT and FREQOUT functions, with 1?s resolution. String functions include concatenation, STRCOMP, LEFT, RIGHT, HEX and VAL functions.

Connected to your PC using USB, ARMmite programming is processed at a rate of more than 10MIPS, compiling according to ARM instructions. With that, Coridium claims you'll get performance comparable to applications written in C.

Coridium also includes library support for I?C, SPI, ASYNC, PWM and more.

Powered from a 7-16Vdc source, the board dissipates about 350mW. The ARMmite also includes a small prototyping area. A $59 evaluation kit is also available.
