NXP announced smallest 32-bit microcontrollers
NXP Semiconductors announced sampling of the smallest 32-bit microcontroller LPC1102. The microcontroller is based on ARM Cortex-M0 processor , and, beside the processor core, packs into 2.17 mm x 2.32 mm package the following components and peripherals: 32 KB Flash memory, 8 KB RAM, 4-channel 10-bit ADC, UART, SPI controller, 11 I/O lines, clock oscillator, four general purpose timers and one system timer.
The LPC1102 is the newest addition to NXP's LPC1100 series of 32-bit microcontrollers. Before the announcement, the LPC1100 family included four microcontrollers - LPC1111, LPC1112, LPC1113 and LPC1114, which differ by size of Flash memory - from 8 KB to 32 KB, size of RAM - from 2 KB to 8 KB, the number of I/O pins and SPI controllers. Other common peripherals for these LPC1100 members are clock oscillator, RS-485/EIA-485 UART, I2C bus interface, 4 timers/counters and 10-bit ADC. LPC1111 - LPC1114 MCUs operate at frequencies up to 50 MHz, and consume no more than 0.03 Watt at 50 MHz. They are manufactured in larger, 7mm x 7mm, package, than newly announced LPC1102 microcontroller.
