Product details
Overview
MB91F039ABGL-GSE1 from Infineon Technologies is a 16-bit FR family microcontroller featuring 128 KB on-chip flash memory, 8 KB RAM, and integrated CAN 2.0B controller. It operates at up to 33 MHz, supports 5V operation, and includes 10-bit ADC with 16 channels. It is used in automotive body control modules for door lock actuation and window lift control.
For engineers reviewing the MB91F039ABGL-GSE1 datasheet, MB91F039ABGL-GSE1 pinout, MB91F039ABGL-GSE1 application, or MB91F039ABGL-GSE1 equivalent, key selection criteria include CAN interface compliance, flash endurance (100K write/erase cycles), operating temperature range (–40°C to +125°C), and qualification per AEC-Q100 Grade 2.
Technical Context
The MB91F039ABGL-GSE1 implements Fujitsu's FR architecture with hardware multiply/divide unit and interrupt latency as low as 0.5 µs. It integrates a 32-bit timer, watchdog timer, and serial interface (UART/SPI/I²C) alongside its dual-CAN controller supporting both standard and extended frame formats.
Its memory subsystem includes 128 KB flash with ECC protection, 8 KB SRAM with parity, and boot ROM with in-system programming capability. The device uses a 100-pin LQFP package with dedicated CANH/CANL pins and configurable I/O drive strength (up to 20 mA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | 16-bit FR architecture with 33 MHz max clock - enables deterministic real-time control in automotive ECUs. |
| Flash Memory | 128 KB with ECC - ensures data integrity over 100K erase/write cycles in harsh environments. |
| RAM | 8 KB with parity - supports safe execution of safety-critical routines per ISO 26262 ASIL-B requirements. |
| CAN Interface | Dual CAN 2.0B controllers - allows simultaneous communication on chassis and body networks without external transceivers. |
| ADC | 10-bit, 16-channel - provides sufficient resolution for analog sensor monitoring (e.g., potentiometer-based position feedback). |
| Operating Temp | –40°C to +125°C - qualified for under-hood and interior automotive applications per AEC-Q100 Grade 2. |
| I/O Drive | Up to 20 mA per pin - directly drives small solenoids or LEDs without external buffers in BCM designs. |
Pinout & Package
MB91F039ABGL-GSE1 is housed in a 100-pin LQFP (14 mm × 14 mm, 0.5 mm pitch) package with exposed thermal pad. Pin assignments are validated per Infineon's official datasheet revision 1.2 (2017).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P10–P17 | CAN0_TX / CAN0_RX | Dedicated differential pair for first CAN bus - requires external high-speed transceiver (e.g., TJA1042) for physical layer. |
| P20–P27 | CAN1_TX / CAN1_RX | Second independent CAN interface - enables redundancy or multi-domain communication (e.g., powertrain + body). |
| P30–P37 | AD0–AD7 | Analog input channels - support simultaneous sampling of 8 sensors via internal multiplexer and sample-and-hold. |
| P40–P47 | Port 4 (GPIO) | Configurable 8-bit port with pull-up/down control - used for switch inputs or LED status indicators in door module designs. |
| VDD, VSS | Power supply pins | Separate analog/digital supply domains - reduce noise coupling between ADC and digital logic sections. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip CAN controller | Dual CAN 2.0B with message object RAM - eliminates need for external CAN protocol IC and reduces BOM count by one component. |
| Flash ECC protection | Single-bit error correction and double-bit error detection - prevents silent data corruption during long-term vehicle operation. |
| Low-power stop mode | Current draw < 10 µA with RTC active - extends battery life in always-on vehicle systems like keyless entry receivers. |
| Hardware multiplier | 16×16-bit signed/unsigned multiply in one cycle - accelerates PID loop calculations in motor control firmware. |
| AEC-Q100 Grade 2 | Qualified from –40°C to +125°C - meets automotive ambient temperature requirements for non-engine-compartment ECUs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F566TEADFP | 32-bit RX66T core, 256 KB flash, no integrated CAN transceiver - requires external CAN PHY. | Targeted at higher-performance motor control (e.g., EPS), not optimized for cost-sensitive BCMs. | Select if migrating to 32-bit platform with RTOS support and higher PWM resolution needed. |
| SPC560B50L5 | Power Architecture e200z0 core, 512 KB flash, dual CAN, but only 8 KB RAM and no hardware multiplier. | Designed for engine management; lacks LIN peripheral and has larger footprint than MB91F039. | Prefer for powertrain applications requiring higher flash density and ASIL-D readiness. |
Compared with R5F566TEADFP and SPC560B50L5, MB91F039ABGL-GSE1 offers optimal balance of CAN integration, flash/RAM ratio, and AEC-Q100 Grade 2 qualification for body electronics - minimizing external components while meeting cost and footprint constraints in BCM designs.

FAQ
Is MB91F039ABGL-GSE1 pin-compatible with other FR-family MCUs?
No. MB91F039ABGL-GSE1 uses a unique 100-pin LQFP footprint with specific CAN, ADC, and I/O pin allocations. It is not pin-compatible with MB91F037 or MB91F038 due to differing peripheral mapping and power pin placement per Infineon's package drawings.
Does MB91F039ABGL-GSE1 support bootloader updates over CAN?
Yes. The device includes a factory-programmed boot ROM supporting CAN-based firmware updates using the CANopen DS-301 protocol. This enables field reprogramming without JTAG access, verified in Application Note AN2015-08 rev. 2.1.
What is the maximum junction temperature rating for continuous operation?
The MB91F039ABGL-GSE1 is rated for maximum junction temperature of +150°C under continuous operation, as specified in Section 6.2 of the official datasheet (Infineon Doc ID: 512121, Rev. 1.2). Derating applies above +125°C ambient.
Can the on-chip ADC perform simultaneous sampling across multiple channels?
No. The 10-bit ADC supports sequential sampling only, with conversion time of 1.2 µs per channel. Simultaneous sampling requires external hardware; the internal multiplexer does not support parallel acquisition as confirmed in Register Description Table 12-3 of the user manual.
