St improves the performance and value of an entry-level 32-bit microcontroller

STM32 super value large capacity series microcontroller provides users with up to 512 KB flash memory and 144 pin package, supporting cost sensitive terminal product upgrading

China, October 21, 2010—— As equipment manufacturers seek product differentiation, add new highlights to their products, and add more value to their customers, the world's leading microcontroller supplier, Italy France semiconductor (New York Stock Exchange code: STM), launched STM32 super value large capacity series microcontrollers, helping designers achieve higher product performance goals at a more competitive price. The new microcontroller is equipped with larger capacity program memory and more abundant on-chip functions, which makes the embedded flash memory capacity range of STM32 super value series microcontroller expand from 16kb to 512KB, and provides a memory capacity scalable microcontroller solution for cost sensitive designers.

Microcontroller is the core of consumer electronic products such as home appliances, multimedia devices and mobile devices. The performance requirements of these products are constantly improving to cope with the increasing and more complex software applications. STM32 microcontroller of STM32 is one of the first Microcontrollers in the market that adopts advanced 32-bit core. It has stronger price competitiveness and higher performance than the proprietary 16 bit microcontroller. At present, there are more than 140 products in this series. The pins and software of the whole series are compatible with each other, providing customers with a wider range of cost performance options, and providing optional functions optimized for market demand, such as built-in USB support function.

Michel buffa, general manager of Italian French semiconductor microcontroller product department, said: "the latest STM32 super value large capacity series has expanded the STM32 super value series product line, opening a more exciting and competitive door for product design using 32-bit microcontrollers. Now, cost sensitive applications can use up to 512KB of flash memory for programming, data storage, and more integrated functions. "

The external memory interface is one of the new functions of STM32 super value and large capacity series products. It can connect various types of external code or data memory, and support the parallel data transmission mode of connecting the LCD display of the built-in controller. At present, there are more and more products using graphic LCD panel, such as washing machine, audio / DVD player and radio frequency remote controller. The design of Italian French semiconductor is directly aimed at these market demands. In addition, the series provides more packaging options for designers, with up to 112 I / O pins, helping designers manage higher density communication between microcontrollers and system components such as sensors, status indicators, wireless subsystems and USB ports. STM32 super value and large capacity microcontroller is also used for meter, motor control and user interface control of industrial and medical equipment.

The main features of STM32 super value large capacity series include:
24 MHz processor; 1.25 DMIPS / MHz
256 to 512 KB flash
External memory interface supporting larger application code storage
24 to 32 KB SRAM
12 x 16 bit timer including motor control timer
