Texas Instruments announced the MSPM0C1104, which is claimed to be the world's most compact Arm-based microcontroller with a footprint of only 1.38 mm2 (in the DSBGA form factor). The solution is intended for use in portable medical devices, personal electronic gadgets and other devices with severely limited space in the case.
The microcontroller is equipped with a 32-bit Arm Cortex-M0+ core with a clock frequency of up to 24 MHz. It has 1 KB SRAM and up to 16 KB flash memory, as well as implemented support for 1×UART, 1×I2C, 1×SPI, 18×GPIO. It has an analog-to-digital converter (ADC) with support for up to ten external channels and a built-in temperature sensor.
The supply voltage can vary from 1.62 to 3.6 V. Various low-power modes are implemented: Run - 87 μA/MHz, Stop - 609 μA at 4 MHz or 311 μA at 32 kHz, as well as Standby - 5 μA with retention of the contents of the SRAM memory. The operating temperature range varies from -40 to +125 °C. The MSPM0C1104 microcontroller from Texas Instruments is available in the following variants:
DSBGA (YCJ) - 8 contacts, 1.6 × 0.861 mm (1.3776 mm2);
SOT-23-THN (DDF) - 8 contacts, 2.9 × 2.8 mm (8.12 mm2);
SOT-23-THN (DYY) - 16 pins, 4.2 × 2 mm (8.4 mm2);
TSSOP (PW) - 20 pins, 6.5 × 6.4 mm (41.6 mm2);
VSSOP (DGS) - 20 contacts, 5.1 x 4.9 mm (24.99 mm2);
WQFN (RUK) - 20 contacts, 3 × 3 mm (9 mm2);
WSON (DSG) - 8 contacts, 2 x 2 mm (4 mm2).
For the new product, Texas Instruments provides reference designs and a set of development tools for rapid prototyping. In particular, a LaunchPad kit with an interface board is available. The price of the microcontroller starts at $0.2 in batches of 1000 pieces.
