DESCRIPTION The Nu Micro® M0A21/M0A23 series is a 32-bit microcontroller based on Arm® Cortex® -M0 core. It provides pact package with highly flexible digital pin function assignment, rich analog peripherals, 40°C to 125°C operating temperature, 2.4V ~ 5.5V operating voltage, CAN 2.0B and LIN interface for robust munication. The Nu Micro® M0A21/M0A23 series targets robust and high operating temperature applications, such as 24 GHz mm Wave radar, Battery Management System (BMS), car lighting, electric window lifter, and power seat. The Nu Micro® M0A21/M0A23 series provide SSOP20 and TSSOP28 package with rich analog and digital functions, which are especially suitable for small form factor applications. SSOP20 provides up to 18 IO pins and TSSOP28 provides up to 26 IO pins. Each IO pin of the M0A21/M0A23 series can be arbitrarily assigned to digital peripherals, such as UART, SPI, and PWM. The M0A21/M0A23 series provides rich analog functions including 17-ch 12-bit 800 k SPS ADC, 1 set of 5-bit DAC and 2 sets of ACMP in both SSOP20 and TSSOP28 package. Moreover, it provides low voltage reset (LVR) and brown-out detector (BOD) to ensure the system safety. The Nu Micro® M0A21/M0A23 series 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, 6ch 16-bit PWM generators, 1 set of CAN 2.0B controller, 2 sets of LIN functions, 5-ch PDMA, 2 sets of UART with One-Wire mode, Ir DA and RS485 functions. Besides, the M0A21/M0A23 series provides two sets of Universal Serial Control Interfaces (USCI) that can be configured as UART, SPI or I2C. The package types of the M0A21/M0A23 series are included SSOP20 (5.3x7.2x1.75 mm) and TSSOP28 (4.4x9.7x1.0 mm). Product Line CAN UART USCI Timer PWM PDMA ADC M0A21 M0A23 Table 1-1 Nu...
