AT32F403AVCT7 PIN To PIN Alternative STM32F411VCT6 STM32F103VCT6 STM32F103VBT6 STM32F103VCT7 flash 256KB

AT32F403AVCT7 PIN To PIN Alternative STM32F103VCT6 flash 256KB Software hardware is completely compatible

1. High compatibility: compatible with Sxx32F103 pins & highly compatible with software
2.M4 main frequency 240MHz (with FPU/DSP), RAM up to 224KB
3.AT32F403ARC/VC can replace the Sxx103RE/VE project just because of insufficient RAM
4. Rich peripherals: I2Cx3, SDIO x 2, SPI/I2S (full duplex) x 4, CANx2, UARTx8, 32-bit Timer, SPIM can be connected to high-speed SPI NOR Flash
5. Built-in sLib function: unique security & secondary development function
6. High computing power, one can replace multiple
7. Support wide operating temperature range (-40-105 degrees)
8. Support small size package: QFN48 6x6mm

ZW = Zero Wait-State, Can reachand SysClk 240 MHz
NZW = non-zero wait-state
The SRAM is expanded to 224 KB on the flash memory support, which is an example of AT32F403AVGT7, and the Flash / SRAM can be set to two configurations:
- ZW: 256 KB, NZW: 768 KB, RAM: 96 KB;
- ZW: 128 KB, NZW: 896 KB, RAM: 224 KB.
Uneart8; usart6 can only be used by the lack of CK pins
SDIO2 is only supported by 4 bits (D0 ~ D3) mode.
Only support 8-bit mode LCD screens.
SPIM = External SPI Flash Memory extension (program execution / data storage / program and data can be encrypted).

AT32F403A Series also imports the SLIB Security Library (Security Library) to support password protection specified range program area, and the programmer burning core algorithm to this area, providing downstream customers for secondary development. In addition, in particular 8 sets of UART serial ports, 2 sets of CAN buss are especially suitable for Internet access applications, and USB device applications do not need external crystals, which can simultaneously enhance the reliability of end products and reduce costs. The AT32F403A can operate in industrial grade temperature range -405 ° C, and provide a series of chip options, high integration, high integration, high-cost first-class market competitiveness, and high-cost market-based resource allocation, high integration and high cost-effective first-class market competitiveness. Industrial Automation, Motor Control, IT (IoT) and Consumer Electronics (Consumer Electronics) and other cost-sensitive and high-performance demand.
