ARM7-based MCUs operate at up to 70 MHz

Philips announced three new additions to its LPC2000 microcontroller family: the LPC2101, the LPC2102, and the LPC2103. Based on the ARM7 TDMI-S architecture, the LPC210x series can operate at speeds up to 70 Mhz (63 MIPs). The MCUs feature fast I/O capabilities, which allow bit-toggling at 17.5 MHz, four times faster than competing ARM MCUs on the market, according to the company. In addition, innovative power management features allow deep power-down mode current consumption (with the real-time clock running) to be below 10 ╬ťA. On-board communication peripherals include two 16C550-compatible UARTs, two fast I2 C-bus interfaces, two SPI/SSP interfaces, four timers with PWM capability, and a 10-bit ADC.

Based on the ARM7 core, the LPC2000 family offers users comprehensive tools and development support environments from traditional 8-bit and 32-bit partners, including Keil, IAR, Nohau, Hitex, Ashling and ARM. Development kits from IAR and Keil, including compilers and development boards, start at $99 and $149, respectively.

Pricing for the three new MCUs is based on the amount of on-board memory. For example, the LPC2101 with 8 kbytes of flash and 2 kbytes of SRAM costs $1.47 in quantities of 10,000. More information on the LPC210x series can be found at www.philips.com/microcontrollers.
