MB91F526LKCPMC-GSE2 Übersicht

The Infineon MB91F526LKCPMC-GSE2 is a 32-bit FR81S RISC automotive microcontroller with 80 MHz CPU clock, 1.0625 MB on-chip Flash, and 176-pin LQFP packaging, designed for low-power high-performance body and chassis ECUs. It operates across 2.5V/3.3V/5V rails and integrates the FR81S core with automotive peripherals including CAN, LIN, and timers.

Key features include 1.0625 MB (1.0625M x 8) Flash program memory, 80 MHz maximum CPU frequency, 176-pin LQFP (24x24 mm) package, and automotive-grade qualification (AEC-Q100). The device supports 2.5V, 3.3V, and 5V operating voltages, and integrates multiple CAN/LIN channels, A/D converters, and timers suitable for automotive body electronics. Per the Arrow listing, the part is supplied in tray packaging.

Technical depth: The MB91F526 belongs to the MB91520 series of FR81S-based microcontrollers. The FR81S core is an Fujitsu-originated (now Infineon) 32-bit RISC architecture optimised for low power consumption and deterministic interrupt response in automotive environments. The 1.0625 MB Flash supports in-application reprogramming for OTA-style firmware updates. The device's automotive qualification and wide operating voltage make it suited to harsh under-hood and body-module environments.

Typical applications include automotive body control modules (BCM), dashboard instrument clusters, HVAC control units, lighting ECUs, and gateway modules. The combination of large Flash, multiple communication peripherals, and automotive-grade reliability suits safety-relevant and convenience body-electronics subsystems. Cross-brand equivalent validation is recommended before substituting.

Design consideration: Ensure PCB layout routes the 176 LQFP power and ground pins to a low-impedance plane; an external 4.7uF bulk decoupling near each VCC cluster plus 100nF per pin is recommended. Always validate pinout against the official Cypress/Infineon datasheet, as suffix variants (GSE2, GSK5E2, GTK5E1) often differ in flash size or peripheral mix.

This page synthesises distributor pricing, drop-in alternatives from the FR81S family, and application guidance for body/chassis designers that go beyond what the manufacturer datasheet alone typically provides.

Typische Anwendungen

MB91F526LKCPMC-GSE2 ist geeignet für 6 Anwendungs: Automotive Body Control Module (BCM), Instrument Cluster MCU, HVAC Control Module, Automotive Lighting ECU, Central Gateway Module, Industrial Automation Controller (Automotive-Grade).

🚗

Automotive Body Control Module (BCM)

The MB91F526LKCPMC-GSE2 fits BCM designs because it integrates 1.0625 MB Flash (enough for lighting/wiper/seat logic), CAN and LIN peripherals for body network gateway duty, and 2.5V/3.3V/5V tolerance for direct connection to 12V battery rails through internal regulators. Its AEC-Q100 qualification ensures BCM-level reliability under hood thermal stress. The 80 MHz FR81S core executes body-logic state machines deterministically while maintaining low quiescent current during key-off sleep. Use this MCU paired with a CAN transceiver such as TJA1042 for the high-speed CAN channel and a LIN SBC like TJA1027 for body sub-nets.

📺

Instrument Cluster MCU

The MB91F526LKCPMC-GSE2 is well suited for instrument cluster designs where its 80 MHz FR81S core drives stepper-motor gauge pointers and segment/LCD displays. Its 176-LQFP exposes ample GPIO for backlight drivers, warning-LED matrices, and CAN-FD diagnostics from the vehicle network. The 1.0625 MB Flash accommodates full cluster firmware including telltale logic and OBD-II routines. Place 100nF ceramic bypass caps adjacent to each VCC cluster and use a 6-layer PCB stack-up to suppress EMI from the cluster's switching regulators.

🌐

HVAC Control Module

For HVAC control units the MB91F526LKCPMC-GSE2 provides deterministic real-time response for blower-speed PWM, blend-door stepper control, and cabin-temperature sensing via its ADC channels. The 1.0625 MB Flash supports climate-control algorithms including PID loops and CAN diagnostics, while 2.5V/3.3V/5V tolerance allows direct interface with 5V sensor signals from NTC thermistors. Its AEC-Q100 grade ensures long-term reliability in the high-humidity cabin environment. Use this MCU alongside a stepper driver and CAN/LIN SBC for full HVAC ECU implementation.

💡

Automotive Lighting ECU

Front-lighting and rear-lighting ECUs benefit from the MB91F526LKCPMC-GSE2's combination of 1.0625 MB Flash (for adaptive-headlamp algorithms), 80 MHz core, and CAN/LIN peripherals for headlamp-level communication. The 176-LQFP package exposes sufficient GPIO for matrix-LED driver enable lines and PWM channels for dimming. AEC-Q100 compliance meets the thermal and reliability demands of headlamp pods. Pair with an LED-matrix driver and a CAN-FD transceiver for full adaptive-driving-beam functionality.

🖥️

Central Gateway Module

The MB91F526LKCPMC-GSE2 can serve as a CAN-to-CAN or CAN-to-LIN gateway in vehicle network architectures, leveraging its multiple CAN channels and LIN interfaces plus 1.0625 MB Flash for routing/filtering tables. The 80 MHz core handles message-rate conversion and bus diagnostics at typical body-network loads. AEC-Q100 grade and 5V tolerance suit the gateway's under-dash mounting position. This design typically pairs the MCU with dual high-speed CAN transceivers and optionally an Ethernet PHY for next-generation gateway modules.

🏭

Industrial Automation Controller (Automotive-Grade)

Industrial designers sometimes select AEC-Q100 MCUs like the MB91F526LKCPMC-GSE2 for harsh-environment controllers where 2.5V/3.3V/5V tolerance and automotive-grade reliability exceed standard industrial ratings. The 1.0625 MB Flash hosts deterministic control firmware, while the 80 MHz core executes real-time motion loops. The 176-LQFP footprint integrates CANopen and DeviceNet protocols natively. This application uses the MCU in factory-automation cells exposed to wide temperature swings and EMI from motor drives.

Auswahlhilfe

Choose MB91F526LKCPMC-GSE2 when designing an automotive body, chassis, or gateway ECU that needs 1.0625 MB Flash, the FR81S 80 MHz core, and AEC-Q100 qualification in a 176-LQFP footprint. For higher Flash requirements, step up to MB91F528USCPMC-GSE2 in the same package. For different temperature grades, select MB91F526LKCPMC-GTK5E1 (extended temp) or MB91F526LWEPMC-GSK5E2 (different screening) - all share the same PCB footprint. Cross-brand alternatives (Renesas RH850, NXP MPC56xx) are NOT drop-in and require PCB redesign. The MB91F526 family is best suited to cost-sensitive body ECUs where FR81S's lower MIPS-per-dollar beats RH850/MPC56xx pricing.

Wichtigste Unterscheidungsmerkmale

  • Largest same-package drop-in ecosystem in the MB91520 series (vs. MB91F528USCPMC-GSE2)
  • 1.0625 MB Flash tier - mid-range sweet spot for body ECUs (vs. MB91F526LWEPMC-GSK5E2)
  • Dual prefix compatibility (MB91 / CY91) (vs. CY91F526LKCPMC-GSE2)

Designhinweise

Estimated: For a 176-LQFP automotive MCU switching at 80 MHz with multiple CAN/LIN buses, place 100nF ceramic decoupling capacitors adjacent to every VCC/VSS pin pair. Add a 4.7uF bulk tantalum or polymer cap within 10mm of each power cluster. Use a 4-layer PCB with a dedicated ground plane below the MCU to minimise EMI coupling from CAN bus edges into the digital core.

Estimated: Power dissipation at 80 MHz full activity is approximately 200-300 mW based on the FR81S core's typical current consumption. With 5V supply and 3.3V IO active, junction temperature rise is ~20-30 C above ambient for the 176-LQFP (theta_JA ~30 C/W with adequate copper). Provide a continuous copper pour on top/bottom layers connected to the thermal pad area for reliable thermal performance under hood mounting.

Do not assume suffix-variant MCUs (GSE2 vs GSK5E2 vs GTK5E1) are bit-for-bit identical. Per cross-reference listings on Avaq and Jakelectronics, suffix codes change temperature grade, peripheral mix, or factory screening. Always validate the ordering table in the manufacturer datasheet before substituting parts in production. Also confirm that the firmware image size fits within the smaller Flash variant's 1.0625 MB boundary.

For CAN bus signals, place the TJA1042/TJA1043 transceiver within 50mm of the MCU's CAN TX/RX pins and route the CANH/CANL traces as a 100 ohm differential pair with ground plane reference. Keep CAN traces away from switching regulator and PWM outputs to prevent radiated EMI coupling. Add a 120 ohm split-termination network at each end of the CAN bus for reliable high-speed CAN-FD communication.
