Product details
Overview
ST92F150CV1QB 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 at up to 24 MHz internal clock, supports 4.5–5.5 V supply, and features two CAN controllers, dual I²C, SPI, and a 10-bit 16-channel ADC - deployed in automotive body control modules requiring robust serial communication and real-time I/O management.
For engineers reviewing the ST92F150CV1QB datasheet, ST92F150CV1QB pinout, ST92F150CV1QB application, or ST92F150CV1QB equivalent, key selection criteria include CAN 2.0B dual-interface capability, J1850 BLPD decoder support for legacy automotive diagnostics, in-application programming (IAP) for field firmware updates, and multi-level interrupt handling across 80 I/O pins with wake-up functionality.
Technical Context
This MCU implements a register-oriented 8/16-bit ST9 core with RUN, WFI, SLOW, HALT, and STOP power modes. Its PLL clock generator accepts 3–5 MHz crystals to derive system clocks, enabling minimum instruction time of 83 ns at 24 MHz. Memory architecture includes segmented addressing via MMU with DPR, CSR, ISR, and DMASR registers for flexible code/data/stack/DMA segment mapping.
The peripheral set integrates two independent 16-bit Multifunction Timers (MFTs) and two Extended Function Timers (EFTs), each supporting input capture and output compare; a dedicated Watchdog Timer (WDT) with hardware/software activation; and a DMA controller that offloads data transfers from CPU overhead - all coordinated through a centralized interrupt controller with nested priority levels up to 7.

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 package only; no J1850 BLPD block | Targeted at next-gen gateways needing larger firmware space but lacking legacy diagnostic support | Select when J1850 is unnecessary and >256 KB Flash is required; not drop-in due to missing BLPD hardware |
| NXP S12XEP100 | 16-bit HCS12X core, 1 MB Flash, CAN FD-ready, but no J1850 hardware decoder or E³™ emulation | Used in newer chassis modules where CAN FD and higher compute throughput outweigh legacy protocol needs | Choose for CAN FD migration path; requires software-based J1850 parsing and external EEPROM for parameter storage |
Compared with ST92F150CV1QB, ST92F250CV2 trades J1850 BLPD for doubled Flash capacity, while S12XEP100 offers CAN FD and larger memory but lacks hardware J1850 and emulated EEPROM - making ST92F150CV1QB uniquely suited for cost-optimized, legacy-diagnostic–enabled body electronics.

FAQ
Does ST92F150CV1QB support CAN FD?
No. ST92F150CV1QB implements CAN 2.0B only, with two fully compliant controllers supporting up to 1 Mbps classical CAN. It lacks CAN FD framing, bit-rate switching, and extended data length capabilities. For CAN FD, consider ST's SPC5 series or NXP's S32K family.
What is the endurance rating of the E³™ emulated EEPROM?
The E³™ block provides 100,000 write/erase cycles and 20-year data retention at 85°C, validated per STMicroelectronics' qualification testing. It uses wear-leveling algorithms across dedicated Flash sectors and includes CRC protection for integrity verification during read/write operations.
Is J1850 BLPD support implemented in hardware or firmware?
J1850 BLPD decoding is implemented entirely in dedicated hardware logic - not CPU-executed firmware. This enables real-time byte-level protocol recognition (GM Class 2, Ford SCP) with zero CPU overhead, deterministic timing, and guaranteed frame synchronization even under heavy interrupt load.
Can ST92F150CV1QB operate from a 3.3 V supply?
No. ST92F150CV1QB requires a 4.5–5.5 V supply per its absolute maximum ratings and internal voltage regulator design. It does not support 3.3 V operation. For 3.3 V automotive MCUs, consider ST's SPC56EL or RH850/F1L families with compatible peripheral sets.
