These chips run at up to 72 MHz, include a 16-bit SAR ADC, an internal OpAmp, a comparator with DAC, and FlexPWM for motor control, plus up to 64 KB flash, 12 KB SRAM, LPI2C, LPSPI, up to four UARTs, and up to 45 GPIOs. They offer pin-to-pin compatibility with the MCX A Series and a migration path from LPC800, LPC1100, and Kinetis MCUs. NXP also released the FRDM-MCXC162 development board ($15) alongside individual chip pricing under 60 cents in quantity, with full MCUXpresso SDK and IDE support. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What are the specs of the new NXP MCX C15 and MCX C16 microcontrollers? The NXP MCX C15 and C16 are Cortex-M23 MCUs running at 48 MHz and 72 MHz respectively, achieving 153 CoreMark. They include up to 64 KB flash, 12 KB SRAM, a 16-bit SAR ADC (up to 18 channels), an internal OpAmp with PGA, a comparator with 8-bit DAC, FlexPWM, up to four LPUARTs, LPI2C, LPSPI, and up to 45 GPIOs, operating from 1.71V to 3.6V across -40°C to 125°C. _daily.dev surfaces microcontroller releases like this for engineers comparing low-cost MCU options._ ### What development board is available for the NXP MCX C162 microcontroller? The FRDM-MCXC162 development board features the 72 MHz MCX C162 MCU with 64 KB flash and 12 KB SRAM, an onboard MCU-Link debugger via USB Type-C, and Arduino, MikroBus, and PMOD headers. It also includes an NXP P3T1755DP temperature sensor, an RGB LED, and reset, ISP, and wake-up buttons, priced at $15 and using FSC-certified packaging. _engineers evaluating new MCU boards can track hardware releases like this one on daily.dev._ ### How does the NXP MCX C1 family compare to Renesas RA0E2 and RA2T1 Cortex-M23 MCUs? The MCX C15 and C16 target the same industrial IoT and appliance class as Renesas RA0E2 and RA2T1, but add a 16-bit SAR ADC, an on-chip OpAmp, a comparator with DAC, and FlexPWM for motor and power control, features not emphasized in the Renesas parts. This positions the NXP family more toward analog-heavy and motor control designs within the same low-cost Cortex-M23 segment. _daily.dev helps hardware engineers weigh MCU options like these when choosing a platform._ ## Similar posts on daily.dev -
