Product details
Overview
MB96F348RSBPQC-GS-N2E2 from Fujitsu Semiconductor is a 16-bit F2MC-16FX microcontroller with 576KB Flash (544KB Flash A + 32KB Flash B), 24KB RAM, dual CAN 2.0B interfaces, 24-channel 10-bit SAR ADC, and 100-pin LQFP package. It operates at up to 56 MHz (17.8 ns instruction cycle) using internal PLL multiplication from a 4 MHz resonator, and supports automotive-grade I/O with programmable Schmitt triggers, pull-ups, and drive strength for EMI control. Used in body control modules requiring real-time CAN communication and sensor acquisition.
For engineers reviewing the MB96F348RSBPQC-GS-N2E2 datasheet, MB96F348RSBPQC-GS-N2E2 pinout, MB96F348RSBPQC-GS-N2E2 application, or MB96F348RSBPQC-GS-N2E2 equivalent, key selection criteria include dual-CAN timing synchronization, Flash B sector protection for firmware updates, 24-channel ADC with external reference switching, low-voltage reset persistence, and dual-clock domain support for RTC and subsystem timing independence.
Technical Context
The MB96F348RSBPQC-GS-N2E2 implements Fujitsu's F2MC-16FX CPU core with 23 addressing modes, barrel shift, and signed multiply/divide instructions - enabling deterministic control-loop execution. Its clock tree separates CPU (up to 56 MHz via PLL) from peripheral domains (subclock, RC, main clock), allowing independent frequency scaling for CAN, ADC, and RTC.
Dual CAN controllers are ISO16845-certified, support bit rates up to 1 Mbit/s, 32 message objects each, and programmable FIFO/loopback modes. The 24-channel 10-bit ADC includes interrupt-on-conversion, external trigger input, and dual independent reference voltage inputs (AVRH/AVRL and AVRH2), enabling ratiometric sensor measurements across varying supply conditions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RH850/F1L | 32-bit RXv2 core, 128 KB RAM, single CAN FD, no dual-reference ADC | Targets higher-performance ADAS-adjacent functions; lacks Flash B partitioning for safe OTA | Choose when CAN FD bandwidth >1 Mbps is required and Flash update safety is handled externally |
| MB96F358R | Same F2MC-16FX core, 416 KB Flash (no Flash B), 16 KB RAM, single CAN, 16-channel ADC | Cost-optimized variant for simpler body nodes without redundant networking or advanced sensor fusion | Choose for entry-level BCMs where dual CAN and 24-channel ADC are not required |
Compared with RH850/F1L and MB96F358R, MB96F348RSBPQC-GS-N2E2 uniquely balances legacy 16-bit deterministic timing, dual-CAN redundancy, Flash B-based firmware resilience, and 24-channel ratiometric ADC - making it optimal for cost-sensitive yet safety-aware automotive body electronics.

FAQ
What is the purpose of Flash B in MB96F348RSBPQC-GS-N2E2?
Flash B (32 KB) is a physically separate memory bank with independent sector protection and erase control. It enables safe firmware updates by allowing application code to run from Flash A while new firmware is written to Flash B - eliminating risk of bricking during over-the-air or dealer flash operations. This architecture meets ISO 26262 ASIL-B requirements for fail-safe update mechanisms.
Does MB96F348RSBPQC-GS-N2E2 support CAN FD?
No. MB96F348RSBPQC-GS-N2E2 implements classical CAN 2.0A/B protocol only, with bit rates up to 1 Mbit/s and ISO16845 conformance. It does not support CAN FD features such as flexible data-rate, extended data length, or CRC enhancements. For CAN FD, consider Socionext's RH850/F1L or Renesas RL78/F14.
How is the dual-reference voltage feature used in practice?
The device provides three analog reference pins: AVRH/AVRL for primary ADC bank and AVRH2 for secondary use. This allows simultaneous ratiometric measurement of two independent sensor groups - e.g., AVRH/AVRL powering cabin temperature sensors while AVRH2 references engine bay pressure sensors - compensating for different supply rail behaviors without external reference ICs.
What packaging and thermal specifications apply to this LQFP variant?
MB96F348RSBPQC-GS-N2E2 uses a 100-pin LQFP (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad. Its rated operating temperature is −40°C to +125°C (automotive grade), junction-to-case thermal resistance is 28°C/W, and maximum power dissipation is 1.2 W at 125°C ambient - validated per AEC-Q100 Grade 2 stress testing.
