STM32 Conventional chip size and the difference between large and small capacity STM32 chips?

This paper mainly discusses the STM32 of conventional chip capacity and the difference between large and small capacity of STM32 chip. The STM32 large capacity chip is a chip that includes up to 512K bytes of flash memory and 64K bytes of SRAM for large capacity. STM32 small capacity chip specific capacity see the table below.

Features of the STM32F103XC,STM32F103XD and stm32f103xe large capacity-enhanced chips:

Large capacity Chip

A: Up to 512K bytes of Flash and 64K bytes of SRAM chip for large capacity.

STM32 small capacity, medium capacity and large capacity model differences

Because Stm32f103xx is a complete series, its members are completely foot-compatible, software and functionally compatible. In the reference manual, stm32f013x4 and stm32f103x6 are classified as small-capacity products, stm32f103x8 and STM32F103XB are classified as medium-capacity products, STM32F103XC, Stm32103xd and Stm32f103xe are classified as large-capacity products, of which our Shenzhou II is the choice of STM32F103XC chip, Shenzhou III is a STM32XE chip, is a large capacity products, capacity is a little, we do products and projects are more reference.

Small-capacity and high-capacity products are an extension of the medium-capacity product (stm32f103x8/b), and the data sheet for small volumes is the STM32F103X4/6 data sheet and the STM32F103XC/D/E data sheet.

Small capacity products have smaller flash memory, RAM space and fewer timers and peripherals. Large-capacity products have large flash memory, RAM space and more on-chip peripherals such as SDIO,FSMC,I2S and DACS, while maintaining compatibility with other products of the same range.

3) Specification Description

A: The Stm32f103xc,stm32f103xd and Stm32f103xe series are 32-bit RISC cores with a working frequency of 72MHz, rich I/O ports, and peripherals connected to two APB buses.

4) with the interface

A: All models contain 3 12-bit adc,4 Universal 16-bit timers and 2 PWM timers, including standard and advanced communication interfaces: up to 2 i²c interfaces, 3 SPI interfaces, 2 I2S interfaces, 1 Sdio interfaces, 5 Usart interfaces, A USB interface and a can interface.

5) Industrial Grade features

A: The stm32f103xx large-capacity Enhanced series works in the -40c~+105c temperature range, with supply voltages from 2.0V to 3.6V, and a range of power-saving modes to ensure low power applications.
