The TI MSPM0C1104, an interesting Arm Cortex-M0+ microcontroller
Article excerpt
The MSPM0C1104 is a cost-optimized mixed-signal MCU on an Arm Cortex-M0+ up to 24 MHz, with 16 KB flash, 1 KB SRAM, and internal 24 MHz/32 kHz oscillators (no crystal needed). It packs one 12-bit SAR ADC (up to 10 channels, 1.5 Msps at VDD reference) with temperature sensor, supply monitor, and selectable 1.4/2.5 V […]
The MSPM0C1104 is a cost-optimized mixed-signal MCU on an Arm Cortex-M0+ up to 24 MHz, with 16 KB flash, 1 KB SRAM, and internal 24 MHz/32 kHz oscillators (no crystal needed). It packs one 12-bit SAR ADC (up to 10 channels, 1.5 Msps at VDD reference) with temperature sensor, supply monitor, and selectable 1.4/2.5 V VREF, plus a single-channel DMA, three 16-bit timers (14 PWM channels), and one each of UART, I²C (Fm+), and SPI (12 Mbps).
It runs 1.62, 3.6 V from −40 to +125 °C, with power modes from RUN (87 µA/MHz) down to STANDBY (~5 µA) and SHUTDOWN (200 nA). It offers up to 18 GPIOs (two 5 V-tolerant), 2-pin SWD, and 100k-cycle flash endurance, with GPIO/ADC counts scaling by package (18/10 on 20-pin down to 6/3 on 8-pin). TI targets battery management, power supplies, metering, lighting, and similar cost- and space-constrained designs.
In round terms: about $0.65 each in ones, dropping to roughly $0.20, 0.30 each at 1,000.
