Naming rules for STM32 chip models

Time:2018-11-09 Views:560
Before STM32F105 and STM32F107 interconnection series microcontrollers, Italian Semiconductor has launched STM32 basic series, enhanced series, USB basic series, enhanced series; new series products continue to use enhanced series of 72MHz processing frequency. The memory includes 64KB to 256KB flash memory and 20KB to 64KB embedded SRAM. The new series uses LQFP64, LQFP100 and LFBGA100 packages. Different packages keep the pin alignment consistent. Combining with the design concept of STM32 platform, developers can re-optimize functions, memory, performance and pin number by choosing products to meet personalized application requirements with minimal hardware changes.

As of July 1, 2010, the market circulation models were:
Basic form: STM32F101R6 STM32F101C8 STM32F101R8 STM32F101V8 STM32F101RB STM32F101VB
Enhancement: STM32F103C8 STM32F103R8 STM32F103V8 STM32F103RBSTM32F103VB STM32F103VE STM32F103ZE
Description of STM32 model: Take the chip of STM32F103RBT6 as an example, this model consists of seven parts, and its naming rules are as follows:
(1) STM32:STM32 represents the 32 bit microcontroller of the ARM Cortex-M3 kernel.
(2) F:F represents the chip family.
(3) 103:103 represents enhanced series.
(4) R: R stands for the number of pins, of which T stands for 36 feet, C for 48 feet, R for 64 feet, V for 100 feet, Z for 144 feet.
(5) The term B: B represents the capacity of embedded Flash, of which 6 represents 32K byte Flash, 8 represents 64K byte Flash, B represents 128K byte Flash, C represents 256K byte Flash, D represents 384K byte Flash, E represents 512K byte Flash.
(6) T: T represents package, H represents BGA package, T represents LQFP package and U represents VFQFPN package.
(7) The term 6:6 represents the working temperature range, of which 6 represents - 40 - 85 C and 7 represents - 40 - 105 C.
