STMicroelectronics Introduces STM32 XL-Density Devices with Extra Flash, RAM and Features

Additional new features of the STM32 XL-density devices include additional high-speed volatile memory (RAM), up to 96KB, which can simplify software design and speed-up execution. Six more timers are also included, increasing flexibility for applications such as motor control, factory automation or power distribution. Furthermore, a Memory Protection Unit (MPU) has been added, which is transparent to existing software but allows new applications to protect specific code or data during execution. This feature permits efficient use of existing certified software modules in projects such as medical or metering equipment, saving the time and cost to re-certify the complete application. The 1MB Flash memory is organized in two banks of 512Kbytes.This dual-bank architecture thereby enables safe upgrading of applications in the field by uploading new software into the second memory bank. The update can then be copied across safely into the main bank, and the process managed to protect against hazards such as power loss while the upgrade is being applied. The new devices complement the existing product lines of the industry’s most extensive Cortex-M3 microcontroller portfolio. The STM32F101Access Line XL density devices continue to provide the low-cost and high-functionality established with the original STM32 Access Line. The STM32F103Performance Line XL density devices extend the existing Performance Line that features faster 72MHz core and extra connectivity like USB and CAN, to applications that require additional memory. With these XL density devices, both lines now comprise versions with 768Kbyte or 1Mbyte Flash memory in a choice of 64-, 100-, or 144-pin packages…
