M252EC2AE

The NuMicro® M252EC2AE is a low-power microcontroller designed with the Arm® Cortex®-M23 core for the Armv8-M architecture. It operates at speeds up to 48 MHz and includes 32 Kbytes of embedded Flash memory and 8 Kbytes of embedded SRAM. Additionally, it has 4 Kbytes of Flash loader memory (LDROM) for In-System Programming (ISP).

This 32-bit microcontroller supports a wide supply voltage range from 1.8 V to 5.5 V and an operating temperature range of -40 °C to +105 °C. It offers low power consumption in various modes, making it suitable for battery-powered IoT applications. The M252EC2AE series provides features like 1-region programmable eXecute-Only-Memory (XOM), 96-bit Unique Identification (UID), and 128-bit Unique Customer Identification (UCID) for enhanced security.

Peripherals include Timers, Watchdog Timers, RTC, 19 GPIOs, up to 11 PWM channels, USCI, 2 UARTs, QSPI, 2 I²C interfaces, ISO-7816-3, and 5 PDMA channels. It also integrates analog front-end blocks such as a 9-channel 12-bit 880 kSPS ADC, temperature sensor, LVR, and BOD. The device supports crystal-less USB 2.0 full-speed device functionality.

The M252EC2AE is available in a TSSOP28 package (4.4 mm x 9.7 mm). Its pin-to-pin compatibility within the same package allows for easy optimization of product features and performance. Target applications include Smart Home devices, Industrial Control, IoT Devices, Security Alarm Systems, and Portable Wireless Data Collectors.
