Product details

64 KB Flash, 10K x 8 RAM — sizing the firmware envelope

The STM32F101V8T6TR: The 64 KB program memory and 10K x 8 SRAM set the boundary for code and data. For a typical sensor-fusion or protocol-gateway application, that Flash holds a bare-metal or RTOS image with the communication stacks (I²C, SPI, UART) and the ADC conversion loop.

The internal oscillator and the built-in POR, PDR, and PVD peripherals reduce external BOM count — no external reset supervisor or crystal needed for basic operation.

The base product number STM32F101 is a long-running STM32F1 family member with broad second-source availability across the STM32F1 value-line portfolio.

Frequently asked questions

What is the difference between STM32F101V8T6TR and STM32F103V8T6?

The STM32F103V8T6 is the higher-performance sibling in the same package and pinout. It runs at 72 MHz (versus 36 MHz) and adds a USB 2.0 full-speed interface and a second 12-bit ADC. Both share the same 64 KB Flash, 10K x 8 SRAM, 80 I/O, and 100-LQFP footprint, making them pin-compatible for a drop-in upgrade if the extra throughput and USB are needed.
