Description

The NuMicro® M0A21EB1AC is a 32-bit microcontroller based on Arm® Cortex®-M0 core. It provides compact package with high 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® M0A21EB1AC 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.

The NuMicro® M0A21EB1AC 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 M0A21EB1AC can be arbitrarily assigned to digital peripherals, such as UART, SPI and PWM. The M0A21EB1AC 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.

The NuMicro® M0A21EB1AC runs up to 48 MHz and supports hardware divider. It provides 16 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 functions, 5-ch PDMA, 2 sets of UART with One-Wire mode, IrDA and RS485 function. Besides, the M0A21EB1AC provides two sets of Universal Serial Control Interfaces (USCI) that can be configured as UART, SPI or I²C.

The package types of the M0A21EB1AC is TSSOP28 (4.4x9.7x1.0 mm).
