$49 BASIC board clocks 60-MHz ARM processor

Tahoe Vista, Calif.—Board maker Coridium Corp. is at it again. This time it's rolling out a very low cost product called the ARMmite.

Priced at less than $50, the ARMmite clocks a 60-MHz ARM (Advanced RISC Machines) LPC2103 processor. Programmable in compiled BASIC, the ARMmite can churn through more than 10 million BASIC lines/s.

The LPC2103 is an ARM7TDMI-S-based 32-bit RISC controller with Thumb extensions. It includes 10-bit A/D (analog-to-digital) converters, and accepts eight analog inputs. The device also packs two 32-bit timers/external event counters, two 16-bit timers/external event counters, a realtime clock with dedicated 32-kHz clock input, and two 16C550-type UARTs.

Six Square Inches

Measuring 2 x 3.2-inches (50 x 80-mm) in size, the ARMmite includes 24 digital I/O lines and an 8-channel A/D (analog-to-digital) converter. The board provides 12-kbytes of code space, 5-kbtes for user data, and 20-kbytes 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 (Universal Serial Bus), ARMmite programming is processed at a rate of more than 10 million instructions/s, 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 I2C, SPI (Serial Peripheral Interface), ASYNC, PWM, and more.

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