MindMotion Announced Entry-level MM32G0001 32-bit MCU Equipping with a 48MHz Arm® Cortex®-M0 core

MindMotion announced its new value-line MM32G0001 microcontrollers. Earlier in 2023, MindMotion had announced its MM32G family, and has since released the G0140, G0160, and G5330 series products. In order to further enrich the MM32G series product portfolio, MindMotion collaborated with upstream and downstream partners to create an entry-level, highly competitive MM32G0001 MCU series. The MM32G0001 MCU series is equipped with a 48MHz Arm^® Cortex^®-M0 core, providing 16KB Flash and 2KB SRAM, as well as rich peripheral resources. The MM32G0001 MCU series is suitable for a wide range of entry-level 32-bit MCU markets and can cover a wide range of upgrade needs for 8/16-bit MCUs.

Optimizing process technology and reducing production costs to help upgrade 8/16-bit MCUs.

ARM-based 32-bit MCUs have been in the market for nearly 20 years. Currently, 32-bit MCUs have gradually covered all aspects of the application market. However, it cannot be ignored that 8/16-bit MCUs, due to their low cost, ease of use, and small package size, still firmly occupy the main position in the entry-level MCU market. Although many 32-bit MCU manufacturers have introduced replacement products for their 8/16-bit counterparts, they have been unable to completely shake the low-cost advantage of 8-bit microcontrollers due to factors such as price and ease of use. However, we have also observed that many mainstream 8/16-bit MCU products have some obvious features, such as using relatively traditional processes, configuring EEPROM, providing a few KB of small-capacity flash, or even OTP (one-time programmable) or MTP (multi-time programmable) with a few tens or hundreds of times, and smaller SRAM configurations, such as a few hundred bytes. With the development of technology, the cost disadvantage of older processes is becoming more and more prominent. Small flash and EEPROM implementations are no longer economical in advanced processes. Therefore, from a technological perspective, the development of 8/16-bit MCUs has reached a bottleneck. With the development of advanced processes, 32-bit MCUs have the opportunity to use the latest technology to achieve costs comparable to or even better than 8/16-bit MCUs.

Observing the above trends, MindMotion worked closely with its partner Shanghai Huahong Grace Semiconductor Manufacturing Corporation ("HHGrace"), relying on the optimization of HHGrace's more than 20 years of solid and reliable embedded flash memory technology, the use of a more stable and large-scale mass-verified 12-inch wafer process platform, the function, performance and cost of the product have been polished in an all-round way, and this cost-effective MM32G0001 series MCU product has been launched under the premise of maintaining the quality goal of MM32.

Unlike some embedded MCU products on the market that experience code loss or reduced read/write times in low- or high-temperature environments, MM32G0001 has been fully verified for its flash erase/write life, data retention capacity, anti-interference capability, and chip reset reliability in various temperature ranges.
