M029G/M030G/M031G Series

NuMicro® M029G, M030G, M031G Series MCU M031GGD2AE M031GTD2AE M031GGC2AE M031GTC2AE M030GGD1AE M030GTD1AE M030GGC1AE M030GTC1AE M029GGC0AE

The M029G/ M030G/ M031G series is based on Arm Cortex-M0 core with 32-bit hardware multiplier/divider. It runs up to 48/72 MHz and features 32Kbytes and 64 Kbytes Flash memory, 2Kbytes, 4 Kbytes and 8 Kbytes SRAM, 2.7V ~ 3.6V operating voltage, 5V I/O tolerant, and -40°C to +105°C operating temperature. Designed for Optical Transceiver Module applications, all of the M029G, M030G and the M031G series have a built-in temperature sensor with ±2°C deviation from -40°C to 105°C and 2 sets of strong I²C with 400K/1MHz slave mode and non-stretch mode. Furthermore, the M031G series, which supports Pilot Tone Modulation, is equipped with a Hardware Manchester Codec with CRC to encode and decode low-frequency dither signal and 1 set of DAC with “Auto Data Generation” function to generate the smooth sine waveform up to 500KHz for the output of Pilot Tone Modulation.

In order to fit the small form factor requirement of the optical module, the M029G, M030G and M031G series provide the QFN 24-pin (3 x 3 mm) and QFN 33-pin (4 x 4 mm) small form factor package with pin-compatible across these 3 series to make the system design and change parts easily.
