It provides compact package with highly flexible digital pin function assignment, rich analog peripherals, -40 ℃ to 125 ℃ operating temperature, 2.4V ~ 5.5V operating voltage and LIN interface for robust communication. The NuMicro\u003csup\u003e®\u003c\/sup\u003e M0A21EC1AC targets on robust and high operating temperature applications, such as 24 GHz mmWave radar, car lighting, electric window lifter, power seat and intelligent power supply.\u003c\/p\u003e\u003cp\u003eThe NuMicro\u003csup\u003e®\u003c\/sup\u003e M0A21EC1AC provides TSSOP28 package with rich analog and digital functions, which are especially suitable for small form factor applications. TSSOP28 provides up to 26 IO pins. Each IO pin of the M0A21EC1AC can be arbitrarily assigned to digital peripherals, such as UART, SPI and PWM. The M0A21EC1AC provides rich analog functions including 17-ch 12-bit 500 KSPS ADC, 1 set of 5-bit DAC and 2 sets of ACMP in TSSOP28 package. Moreover, it provides low voltage reset (LVR) and brown-out detector (BOD) to ensure the system safety.\u003c\/p\u003e\u003cp\u003eThe NuMicro\u003csup\u003e®\u003c\/sup\u003e M0A21EC1AC runs up to 48 MHz and supports hardware divider. It provides 32 Kbytes Flash memory, 4 Kbytes SRAM and 2 Kbytes LDROM for ISP (In-System Programming) feature for easily firmware update. It is equipped with plenty of peripherals including up to four 32-bit timers, 6-ch 16-bit PWM generators, 2 sets of LIN function, 5-ch PDMA, 2 sets of UART with One-Wire mode, IrDA and RS485 functions. Besides, the M0A21EC1AC provides two sets of Universal Serial Control Interfaces (USCI) that can be configured as UART, SPI or I²C.\u003c\/p\u003e\u003cp\u003eThe package types of the M0A21EC1AC is TSSOP28 (4.4x9.7x1.0 mm).\u003c\/p\u003e\u003ch5\u003eApplications\u003c\/h5\u003e\u003cul\u003e\n\u003cli\u003e24GHz mmWave radar\u003c\/li\u003e\n\u003cli\u003eCar lighting\u003c\/li\u003e\n\u003cli\u003eElectric window lifter\u003c\/li\u003e\n\u003cli\u003ePower seat\u003c\/li\u003e\n\u003cli\u003eIntelligent power supply\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch5\u003eKey Features\u003c\/h5\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCore\u003c\/strong\u003e\u003cul\u003e\n\u003cli\u003eArm\u003csup\u003e®\u003c\/sup\u003e Cortex\u003csup\u003e®\u003c\/sup\u003e-M0 core running up to 48 MHz\u003c\/li\u003e\n\u003cli\u003eSingle-cycle 32-bit hardware 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\u003e32 KB Flash for program code\u003c\/li\u003e\n\u003cli\u003eUp to 4 KB SRAM\u003c\/li\u003e\n\u003cli\u003e2 KB SRAM\u003c\/li\u003e\n\u003cli\u003eSupports In-System-Program (ISP) and In-Application-Program (IAP) application code update\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePeripheral DMA (PDMA)\u003c\/strong\u003e\u003cul\u003e\u003cli\u003eSupports up to 5 independent configurable channels for automatic data transfer between memories and peripherals\u003c\/li\u003e\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCRC calculation unit\u003c\/strong\u003e\u003cul\u003e\u003cli\u003eSupports CRC-CCITT, CRC-8, CRC-16 and CRC-32 polynomials\u003c\/li\u003e\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClocks\u003c\/strong\u003e\u003cul\u003e\n\u003cli\u003eInternal 48 MHz RC oscillator (frequency drift \u0026lt;± 2 % @ - 40 ℃ ~ 105°C, \u0026lt;± 3 % @- 40 ℃ ~ 125 °C)\u003c\/li\u003e\n\u003cli\u003eInternal 38.4 kHz RC with calibration (frequency drift \u0026lt;± 10 % @ - 40 ℃ ~105 ℃ , \u0026lt;
