Frequently Asked Questions
Q1: What CPU core does ST10F275‑CEG use?
A: It adopts 16‑bit enhanced C166 core up to 64 MHz, built‑in DSP MAC multiply‑accumulate unit.
Q2: What are the onboard Flash and RAM sizes?
A: 768KB on‑chip Flash, total 64KB internal RAM.
Q3: Can ST10F275‑CEG be used for automotive applications?
A: Yes. Dual CAN2.0B interface and ‑40℃~+125℃ automotive‑grade temperature, widely used for automotive ECU and harsh industrial real‑time control.
Q4: Difference between ST10F275‑CEG and ST10F276‑CEG?
A: Pin‑to‑pin hardware compatible. ST10F276‑CEG has larger 832KB Flash and 68KB RAM. Hardware replacement is allowed, but firmware must match memory size, cross‑model firmware flashing is prohibited.
Q5: What do CEG and CFG suffixes stand for?
A: ST10F275 is only base series name, not full ordering PN. CEG:144‑PQFP,‑40℃~+125℃ automotive grade, RoHS lead‑free. CFG: same package,‑40℃~+85℃ industrial grade, cannot substitute CEG for automotive projects.
Q6: What is the correct operating supply voltage?
A: This is a pure 5V device, 4.5V‑5.5V input. 3.3V power supply will lead to abnormal operation.
Q7: Any pin‑compatible cross‑brand alternatives?
A: No direct drop‑in cross‑brand replacement. You may refer to other ST10 family MCUs for software migration, verify memory and peripherals before use.
Q8: How to get datasheet, pinout or bulk quotation?
A: Submit quick inquiry form for datasheets, programming documents and volume pricing.
