Frequently Asked Questions
Q1: What is the difference between ST10F276‑CFG and ST10F275‑CEG?
A: ST10F276‑CFG features 832KB Flash / 68KB RAM, packaged in 144‑PQFP, upgraded memory compared with ST10F275‑CEG.
Q2: What core does ST10F276‑CFG adopt?
A: 16‑bit C166 core running up to 64MHz, integrated single‑cycle MAC DSP accelerator.
Q3: What temperature grade for ST10F276‑CFG?
A: Extended commercial grade,‑40℃ ~ +85℃, not automotive‑grade‑40~125℃.
Q4: Can it work with 3.3V power supply?
A: No. It is a 5V‑only device, operating voltage 4.5V‑5.5V, 3.3V domain is not supported.
Q5: Difference among suffix CFG / R / S / Z?
A: ST10F276 is main model. Suffix stands for different packages. CFG = 144‑PQFP. R/S/Z are other package versions, pinout differs, cannot drop‑in replace.
Q6: Can ST10F276‑CFG replace ST10F273?
A: Not direct replacement. ST10F273 lacks 320KB XFLASH, max RAM only 32KB. No internal hardware detection register. Shared‑PCB needs external pull‑up resistor.
Q7: How to get datasheet and bulk quotation?
A: Submit quick inquiry for datasheet, pinout guide, evaluation solution and volume price.
