{"product_id":"m254sd2ae","title":"M254SD2AE","description":"\u003cp\u003eThe NuMicro M254SD2AE 32-bit microcontroller is based on Arm Cortex-M23 core using Armv8-M architecture with COM\/SEG LCD driver. It runs up to 48 MHz and features 64 Kbytes Flash memory, 8 Kbytets SRAM, 1.75V ~ 5.5V wide operating voltage, 5V I\/O tolerance, and -40℃ to 105℃ operating temperature.\u003c\/p\u003e\u003cp\u003eM254SD2AE includes a 8 x 28, 6 x 30, 4 x 32 COM\/SEG LCD driver with selectable bias voltage and duty, and it also built-in charge-pump to support 3V to 5V wide voltage of LCD panel.\u003c\/p\u003e\u003cp\u003eM254SD2AE provides plenty of peripherals such as Timers, Watchdog Timers, RTC, 5 channels of PDMA, 3 sets of UART, 1 setof Universal Serial Control Interface (USCI), 1 set of SPI\/ I²S, 1 set of I²C, 1 set of ISO-7816-3, 6 channels of basic PWM, making it highly suitable for connecting comprehensive external modules. It also integrates high performance analog circuit, such as 16 channels of 12-bit 730 kSPS ADC, and a temperature sensor to reduce external components.\u003c\/p\u003e\u003cp\u003eSupported packages LQFP64 ( 7 mm x 7 mm ) with pin-compatible for different part numbers make the system design and parts change easily.\u003c\/p\u003e\u003ch5\u003eApplications\u003c\/h5\u003e\u003cul\u003e\n\u003cli\u003eHandheld meter\u003c\/li\u003e\n\u003cli\u003eThermostat\u003c\/li\u003e\n\u003cli\u003eSmart Home \/ Home Appliance\u003c\/li\u003e\n\u003cli\u003eIndustrial Control \/ Industrial Automation\u003c\/li\u003e\n\u003cli\u003eTemperature\/Humidity Logger\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch5\u003eKey Features\u003c\/h5\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Characteristics\u003c\/strong\u003e\u003cul\u003e\n\u003cli\u003eVoltage range: 1.75V ~ 5.5V\u003c\/li\u003e\n\u003cli\u003eTemperature range: - 40 ℃ ~ 105 ℃\u003c\/li\u003e\n\u003cli\u003eEFT 4.4 KV\u003c\/li\u003e\n\u003cli\u003eESD HBM 7 KV\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCore\u003c\/strong\u003e\u003cul\u003e\n\u003cli\u003eArm Cortex-M23 core using Armv8-M architecture, running up to 48 MHz, without TrustZone\u003c\/li\u003e\n\u003cli\u003e32-bit hardware multiplier\/divider\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMemories\u003c\/strong\u003e\u003cul\u003e\n\u003cli\u003e64 KB Flash\u003c\/li\u003e\n\u003cli\u003e8 KB SRAM\u003c\/li\u003e\n\u003cli\u003e4 KB LDROM\u003c\/li\u003e\n\u003cli\u003e1-region eXecute-Only-Memory (XOM)\u003c\/li\u003e\n\u003cli\u003eISP\/ICP\/IAP programming\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClocks\u003c\/strong\u003e\u003cul\u003e\n\u003cli\u003e4 ~ 32 MHz external high speed crystal oscillator (HXT) for precise timing operation\u003c\/li\u003e\n\u003cli\u003e32.768 kHz external low speed crystal oscillator (LXT) for RTC function and low-power system operation\u003c\/li\u003e\n\u003cli\u003e48 MHz internal high speed RC oscillator (HIRC) for system operation (Factory pre-trimmed to ±0.25% and frequency deviation ±2.5% over entire temperature from -40°C ~ 105 °C)\u003c\/li\u003e\n\u003cli\u003e4.032 MHz internal high speed RC oscillator (MIRC) for system operation\u003c\/li\u003e\n\u003cli\u003e38.4 kHz internal low speed RC oscillator (LIRC) for Watchdog Timer and wake-up operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCOM\/SEG LCD Driver\u003c\/strong\u003e\u003cul\u003e\n\u003cli\u003e8 x28, 6 x 30 \u0026amp;
