Product Overview
The ST10R167-Q3 is a reliable 16-bit ROMless microcontroller based on STMicroelectronics ST10 core. It runs at up to 25 MHz with single-cycle instruction execution for excellent real-time performance. This ROMless chip relies on external Flash or EPROM via 8/16-bit bus interface, supporting external storage up to 16MB for flexible capacity expansion and convenient firmware upgrades.It integrates 4KB on-chip RAM, including 2KB dual-port RAM and 2KB extension RAM. Equipped with rich peripherals such as 16-channel 10-bit ADC and multi-function serial interfaces, it is widely used in automotive control, industrial automation and embedded systems.
Core Advantages
Efficient High-Speed 16-Bit Pipeline
Adopts 4-stage pipeline architecture at 25MHz. Most instructions complete within one clock cycle (80ns), delivering strong computing capability for real-time tasks.
Flexible ROMless Memory Design
No on-chip program memory, supporting external memory up to 16MB. The configurable bus interface facilitates large-capacity firmware deployment and updates.
Powerful Interrupt & Data Handling
8-level interrupt priority ensures fast response. The built-in PEC realizes automatic data transmission, reducing CPU occupancy.
Industrial-Grade Peripherals
Integrated high-precision timers, 16-channel ADC and multiple serial ports feature strong anti-interference, adapting to harsh industrial operating environments.

Frequently Asked Questions
Q1: Is your current stock inventory of the ST10R167-Q3 completely original and factory-new?
A: Yes, all ST10R167-Q3 microcontrollers are 100% brand-new genuine products from STMicroelectronics, stored under standard ESD protection conditions.
Q2: What does the “ROMless” designation mean when designing a system with this MCU?
A: This chip has no built-in program memory. It must load program code from external Flash or EPROM via external bus after power on.
Q3: How does the integrated Peripheral Event Controller (PEC) improve real-time loop handling?
A: PEC acts as a dedicated data transfer unit. It realizes automatic data transmission between peripherals and RAM, lowering CPU load and improving real-time performance.
Q4: How can our technical department request hard-to-find legacy documentation, register configurations, or volume pricing?
A: Please fill in the Quick Inquiry form on this page. We will send relevant technical documents and quote within 24 hours.
