Product details
Overview
ST92F150CV9TB from STMicroelectronics is an 8/16-bit single-voltage Flash microcontroller with integrated CAN 2.0B and J1850 BLPD interfaces, 256 KB Flash, 8 KB RAM, and 1 KB emulated EEPROM (E³™). It operates from 4.5–5.5 V at up to 24 MHz internal clock (83 ns min. instruction time) and supports RUN, WFI, SLOW, HALT, and STOP power modes. Used in automotive body control modules requiring robust serial communication and in-system programmability.
For engineers reviewing the ST92F150CV9TB datasheet, ST92F150CV9TB pinout, ST92F150CV9TB application, or ST92F150CV9TB equivalent, key selection considerations include its dual CAN 2.0B interfaces, J1850 BLPD decoder for legacy vehicle networks, 10-bit 16-channel ADC, and support for In-Application Programming (IAP) in automotive-grade temperature range.
Technical Context
This MCU implements a register-oriented 8/16-bit ST9 core with memory management unit (MMU) supporting 16-Kbyte pages and 64-Kbyte segments. Its interrupt system features multi-level nesting (7 priority levels), 4 fast external interrupts plus NMI, and dedicated wake-up management via WUIMU across up to 16 pins.
The peripheral set includes two independent 16-bit Extended Function Timers (EFTs) and two 16-bit Multifunction Timers (MFTs), each with input capture and output compare, plus a standard timer independent of the PLL clock generator. Communication is served by SPI, dual I²C, SCI-M (multiprotocol), SCI-A (LIN-capable), J1850 BLPD, and two CAN 2.0B controllers - all accessible via up to 80 I/O pins.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ST92F250CV2 | Higher Flash (512 KB), same core/peripherals but LQFP100 only; no J1850 BLPD block | Targeted at next-gen ECUs needing larger code space but not legacy J1850 support | Select when J1850 is unnecessary and >256 KB Flash is required; pin-compatible but firmware not drop-in due to peripheral register differences |
| NXP SPC560B50L3 | 32-bit Power Architecture core, 512 KB Flash, CAN FD, no J1850 or E³™; requires external EEPROM | Designed for ASIL-B safety-critical powertrain applications, not body electronics | Choose for new designs requiring functional safety compliance (ISO 26262) and CAN FD bandwidth; not suitable for J1850-dependent legacy systems |
Compared with ST92F150CV9TB, ST92F250CV2 offers double Flash capacity but drops J1850 BLPD - limiting retrofit compatibility, while SPC560B50L3 targets safety-critical domains with higher performance but adds complexity and cost where legacy protocol support is essential.

FAQ
What is the operating temperature range for ST92F150CV9TB?
The ST92F150CV9TB is qualified for automotive operation over –40 °C to +125 °C ambient temperature (AEC-Q100 Grade 2), with validated performance across this range for voltage regulation, Flash programming, and CAN/J1850 communication timing margins.
Does ST92F150CV9TB support CAN FD or only classical CAN 2.0B?
ST92F150CV9TB supports only ISO 11898-1 CAN 2.0B (Classical CAN) with bit rates up to 1 Mbps. It does not implement CAN FD features such as flexible data-rate, extended data length, or CRC enhancements - confirmed in Section 14.8 of Doc ID 8848 Rev 7.
How is the J1850 BLPD functionality implemented in hardware?
J1850 BLPD is implemented as a dedicated on-die hardware decoder block that directly processes PWM and VPW frames per SAE J1850, extracting message IDs and data without CPU intervention. It connects to dedicated J1850+/J1850− pins and generates interrupts upon valid frame reception - detailed in Section 14.9 of the datasheet.
Is the E³™ (emulated EEPROM) accessible during normal program execution?
Yes - E³™ is fully accessible during RUN mode via standard memory-mapped reads/writes. Write/erase operations are atomic and interruptible, with status flags indicating completion. The emulation layer handles wear leveling and page management transparently, requiring no external EEPROM driver code.
