Embedded World: TI is jumping into the Cortex-M0+ with both feet


"TI is building the industry's most comprehensive portfolio of Arm Cortex-M0+-based microcontrollers," said TI MCU vp Vinay Agarwal.

The two, known as MSPM0, are originally two subgroups, one clocked at 32 MHz and the other at 80 MHz.

  • MSPM0L. .
    32 MHz CPU, up to 64 Kbytes of flash memory, up to 4 Kbytes of RAM memory
    Analog options: zero-drift op amps, TIA, 12-bit ADC 1 Msample/s, fast comparator
  • MSPM0G..
    80 MHz CPU, up to 128 Kbytes of flash memory, up to 32 Kbytes of RAM
    Analog parameters: operational amplifiers with zero drift, dual 14-bit ADCs 250 ks./s, dual 12-bit ADCs 4 Msec. /s DAC
    CAN interface options up to 5 Mbps including 2.0A, 2.0B or FD (Flexible Data Rate)

Electronics Weekly saw a zero-drift op amp for the first time, which could make interfacing with precision sensors a lot easier, but a search of previous datasheets turned up … …nothing – so more information was requested.
UPDATE: TI has provided a link to the MSPM0L130x datasheet (see below), which includes a bit more: 0.5 µV/°C drift with clipping, 10 pA input bias, and a built-in programmable gain stage up to 32x. It also states that the MCU's comparator has a fast 40ns propagation delay mode, as well as a 1µA low-power mode and an 8-bit reference DAC.

Packages will consist of 16 to 64 contacts, and the smallest planned size of flash memory is 16 Kbytes.

In terms of power, taking the MSPM0G110x range (block diagram on the left) almost at random, they will run at 96 µA/MHz (CoreMark), sleep at 200 µA (4 MHz) sleep at 50 µA (32 kHz), standby at 1, 5 µA (RTC and SRAM active) and shutdown to 100 nA (with I/O wakeup).

For prototyping, there are hardware development kits for the MSPM0L1306 and MSPM0G3507, and there will be an MSPM0 software development kit with drivers, libraries, over 200 code examples and subsystem projects.

"Design support resources and coding tools, including graphical tools that simplify device configuration, help developers code once and then scale future MSPM0-based designs," said TI.
