NXP has introduced its lowest power 32-bit Cortex-M3
microcontroller.
The LPC1300 series, based on the Cortex-M3 Rev2 core operates at
70MHz and consumes approximately 200µA per MHz.
“The new LPC1300 series has the tightest integration and the
most advanced power management in this class of products while
offering unbeatable value," said Geoff Lees, v-p and general
manager, microcontroller product line, NXP Semiconductors.
Lees sees ARM's Cortex M3 design as a
higher performance, lower power alternative to the ARM7. "We were
impressed with version two of the Cortex M3. It added a wake-up
interrupt controller and software power-down,” said Lees.
Designed to provide a link between 16- and 32-bit applications, the
microcontrollers are pin-compatible with the
Cortex-M0 based LPC1100 series and
deliver up to 32kbyte of flash memory, 8kbyte of SRAM memory,
low-cost USB and up to 42 general purpose I/O pins.
With a built-in Nested Vectored Interrupt Controller (NVIC) and
requiring a single 3.3V power supply, the chip uses power
management unit to minimise power consumption in Sleep, Deep-Sleep
and Deep-power-down modes.
The LPC1300 also enables in-system programming and in-application
programming via on-chip bootloader software and offer a range of
serial interfaces including high speed USB 2.0 with on-chip PHY,
UART, SSP/SPI controller and I2C-bus interface.
It will be available from September 2009.
