ARM7 MCUs Race At Speeds Up To 70 MHz

Expanding the LPC2000 microcontroller family, the LPC2101, LPC2102, and LPC2103 employ ARM7 TDMI-S architectures to deliver operating at speeds up to 70 MHz (63 MIPs). The MCUs also feature fast I/O capabilities, which allow bit toggling at speeds to 17.5 MHz and power management features that achieve a power-down mode consumption of less than 10 μA with the real-time clock running. Peripherals include two 16C550-compatible UARTs, two I2C interfaces, two SPI/SSP interfaces, four timers with PWM capability, and a 10-bit a/d converter. Prices for the LPC2101 (8 KB flash/2 KB SRAM), LPC2102 (16 KB flash/4 KB SRAM), and LPC2103 (32 KB flash/8 KB SRAM) are $1.47, $1.85, and $2.20 each/10,000, respectively. Development kits including compilers and development boards are available from third-party partners with prices starting at $99 each. ROYAL PHILIPS ELECTRONICS, San Jose, CA. (408) 617-4700.
