Product details
Overview
ST92F150CR9TB 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 0–24 MHz crystal or RC input, and delivers 83 ns minimum instruction time. Used in automotive body control modules requiring robust serial networking and in-system programmability.
For engineers reviewing the ST92F150CR9TB datasheet, ST92F150CR9TB pinout, ST92F150CR9TB application, or ST92F150CR9TB equivalent, key selection criteria include dual CAN 2.0B interface support, J1850 BLPD decoding capability, 10-bit 16-channel ADC, multi-level interrupt handling across 80 I/O pins, and In-Application Programming (IAP) for field firmware updates.
Technical Context
The ST92F150CR9TB 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 precise timing control independent of main oscillator stability.
It integrates two full CAN 2.0B Active interfaces with dedicated message buffers and error counters, plus a J1850 Byte Level Protocol Decoder supporting GM/LIN-compatible diagnostics. The memory management unit (MMU) enables 64-Kbyte segment addressing and supports code/data separation via CSR, ISR, and DPR registers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ST92F250CV2 | Same ST9 core, 512 KB Flash, 16 KB RAM, LQFP100 package; adds external memory interface enhancements and higher-speed PLL range | Targeted at complex gateways requiring larger code space and external boot ROM support | Select when >256 KB Flash or external memory expansion is required; pin-compatible but requires updated memory map configuration |
| NXP S12XEP100 | 16-bit HCS12X core, 1 MB Flash, 64 KB RAM, dual CAN, but no J1850 BLPD hardware decoder | Used in high-end powertrain ECUs where J1850 is absent and CAN FD readiness is prioritized | Choose only if J1850 decoding can be implemented in software or omitted; requires full toolchain and peripheral driver migration |
Compared with ST92F150CR9TB, ST92F250CV2 offers double Flash/RAM and enhanced EXTMI timing, while S12XEP100 trades J1850 hardware acceleration for greater compute headroom and CAN FD readiness-neither provides identical protocol offload capability in legacy automotive diagnostics.

FAQ
Does ST92F150CR9TB support CAN FD?
No. ST92F150CR9TB implements CAN 2.0B only, with bit rates up to 1 Mbps and full object buffer management. It lacks the arbitration bit rate switching, flexible data-rate payload extension, and ISO 11898-1:2015 compliance required for CAN FD. For CAN FD migration paths, ST recommends the SPC58x or STM32H7 series.
What is the maximum operating temperature for ST92F150CR9TB?
The ST92F150CR9TB is qualified per AEC-Q100 Grade 2, supporting continuous operation from −40 °C to +105 °C ambient temperature. Junction temperature must remain below 125 °C under worst-case power dissipation, verified via thermal simulation using the 14 × 14 mm LQFP100 package's θJA = 42 °C/W specification.
Is SWIM debug supported in production firmware?
Yes. The Single-Wire Interface Module (SWIM) remains active in all operating modes-including RUN, WFI, and HALT-and supports full read/write access to registers, RAM, and Flash during live operation. Production firmware may disable SWIM via option byte configuration, but default state enables debugging without hardware modification.
How many I/O pins support wake-up from STOP mode?
Up to 16 pins-programmable across Ports A through E-can generate wake-up events from STOP mode. Each pin supports edge-selectable (rising/falling/both) detection and feeds into the Wake-up / Interrupt Lines Management Unit (WUIMU), which prioritizes and routes interrupts before CPU restart.
