Overview

2.2.1

ARM® Cortex™-M3 core with embedded Flash and SRAM

The ARM Cortex™-M3 processor is the latest generation of ARM processors for embedded

systems. It has been developed to provide a low-cost platform that meets the needs of MCU

implementation, with a reduced pin count and low-power consumption, while delivering

outstanding computational performance and an advanced system response to interrupts.

The ARM Cortex™-M3 32-bit RISC processor features exceptional code-efficiency,

delivering the high-performance expected from an ARM core in the memory size usually

associated with 8- and 16-bit devices.

The STM32F100xx value line family having an embedded ARM core, is therefore

compatible with all ARM tools and software.

2.3

Embedded Flash memory

Up to 128 Kbytes of embedded Flash memory is available for storing programs and data.

2.4

CRC (cyclic redundancy check) calculation unit

The CRC (cyclic redundancy check) calculation unit is used to get a CRC code from a 32-bit

data word and a fixed generator polynomial.

Among other applications, CRC-based techniques are used to verify data transmission or

storage integrity. In the scope of the EN/IEC 60335-1 standard, they offer a means of

verifying the Flash memory integrity. The CRC calculation unit helps compute a signature of

the software during runtime, to be compared with a reference signature generated at link-

time and stored at a given memory location.

2.5

Embedded SRAM

Up to 8 Kbytes of embedded SRAM accessed (read/write) at CPU clock speed with 0 wait

states.
