M091YD2AE

M091YD2AE

The M091YD2AE is 32-bit microcontroller is designed for analog sensor applications. It features rich analog peripherals including 4 sets of 8 MHz gain bandwidth (GBW) with 50 µV input offset voltage operational amplifier (OPA), 4 sets of 12-bit DAC, 16 channels of 2 MSPS 12-bit SAR ADC, built-in temperature sensor with ±1.6°C deviation from 0°C to 70°C and ±2°C deviation from -40°C to 105°C.

The M091YD2AE is based on Arm Cortex-M0 core with 32-bit hardware multiplier/divider. It runs up to 72 MHz and features 64 Kbytes Flash memory, 8 Kbytes SRAM, 2.7V ~ 3.6V operating voltage, 5V I/O tolerance, and -40°C to +105°C operating temperature.

The M091YD2AE provides plenty of peripherals including up to 6 sets of 32-bit timers, 1 set of UART with RS485 and One-wire mode, 1 set of SPI, 2 sets of I²C supporting 1 MHz Slave mode, 6 channels of 16-bit BPWM, and up to 7 channels of PDMA to offload CPU loading.

To fit the small form factor requirement of the analog sensor, the M091YD2AE provides the QFN 48-pin (5x5 mm) small form factor package to make the neat and compact PCB design.

For the development system, Nuvoton provides the NuMaker evaluation board and Nuvoton Nu-Link debugger. The 3rd Party IDE such as Keil MDK, IAR EWARM, and Eclipse IDE with GNU GCC compilers are also supported.
