NXP has unleashed a new 32-bit processor for entry-level IoT designs. The new chip adds to the firm’s LPC800 series of 32-bit ARM 30 MHz Cortex-M0+ based microcontrollers.
The new LPC84x MCUs claim 10x higher performance, 3x times more power savings and 50 percent smaller code-size than 8- or 16-bit microcontrollers
“We’re extremely excited to be ramping the LPC84x family into production together with our broad base of customers,” said Geoff Lees, senior vice president and general manager of the microcontroller business at NXP. “This new family further extends LPC800’s unique innovative features over aging, proprietary 8-bit MCUs.”
For power efficiency, the LPC84x devices feature a unique way to configure the device without CPU intervention. Upon power-up, its fast access initialization memory (FAIM) allows the clocks of the LPC84x microcontroller to be started in a low frequency mode, keeping startup current consumption to a minimum.
Within the LPC84x series, the LPC845 offers an additional flexible capacitive touch-sensing solution, which can operate in sleep and deep sleep modes, allowing for very low power performance.
The LPC845 can handle up to nine capacitive buttons in different sensor configurations — such as a slider, rotary or a button matrix.
The MCU series includes powerful 32-bit State-Configurable Timer with PWM, advanced DMA, autonomous serial interfaces and patented IO switch matrix, where any peripheral function can be assigned to any of the 56 GPIO, enabling low-cost PCBs.
In the Press release, the firm states that developers can leverage the benefits of LPC800 series of feature-rich, entry-level MCUs at aggressive 8-bit pricing. The series offers options of 64 KB of integrated flash memory and 16 KB SRAM, with a 12-bit ADC, dual 10-bit DAC, and a selectable output free-running oscillator (FRO).
Package options include LQFP64, LQFP48, HVQFN48 and HVQFN33.
Evaluation kits and software packages are available starting in Q3 2017. For further details, view the full Press release.
