M0A23OC1ACU

The NuMicro® M0A23OC1ACU is an automotive 32-bit microcontroller based on Arm® Cortex®-M0 core which is AEC-Q100 Grade 1 qualified. It provides compact 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 communication. The NuMicro® M0A23OC1ACU targets robust and high operating temperature applications, such as Battery Management System (BMS), car lighting, electric window lifter, and power seat.

The NuMicro® M0A23OC1ACU provides SSOP20 package with rich analog and digital functions, which are especially suitable for small form factor applications. SSOP20 provides up to 18 IO pins. Each IO pin of the M0A23OC1ACU can be arbitrarily assigned to digital peripherals, such as UART, SPI and PWM. The M0A23OC1ACU provides rich analog functions including 17-ch 12-bit 500 KSPS ADC, 1 set of 5-bit DAC and 2 sets of ACMP in SSOP20 package. Moreover, it provides low voltage reset (LVR) and brown-out detector (BOD) to ensure the system safety.

The NuMicro® M0A23OC1ACU 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, 1 set of CAN 2.0B controller, 2 sets of LIN functions, 5-ch PDMA, 2 sets of UART with One-Wire mode, IrDA and RS485 functions. Besides, the M0A23OC1ACU provides two sets of Universal Serial Control Interfaces (USCI) that can be configured as UART, SPI or I²C.

The package types of the M0A23OC1ACU is SSOP20 (5.3 x 7.2 x 1.75 mm).
