Infineon Technologies MB96F348RSAPMCR-GSE2

Overview

MB96F348RSAPMCR-GSE2 from Infineon Technologies (formerly Cypress) is a 16-bit F2MC-16FX microcontroller with dual-clock architecture, 576 KB on-chip Flash (544 KB + 32 KB), 24 KB RAM, dual CAN 2.0A/B controllers, 24-channel 10-bit SAR ADC, and 2-channel alarm comparator. It operates at up to 56 MHz CPU frequency via internal PLL (17.8 ns instruction cycle), supports LIN/SCI/USART/I²C, and targets automotive body control modules requiring deterministic real-time response and functional safety support.

For engineers reviewing the MB96F348RSAPMCR-GSE2 datasheet, MB96F348RSAPMCR-GSE2 pinout, MB96F348RSAPMCR-GSE2 application, or MB96F348RSAPMCR-GSE2 equivalent, key selection criteria include dual-CAN channel count, Flash memory partitioning (Flash A/B), subclock RTC calibration capability, external bus interface timing programmability, and low-voltage reset persistence in single-clock mode (suffix "S").

Technical Context

The MB96F348RSAPMCR-GSE2 implements the F2MC-16FX CPU core with RISC-like pipelined execution, 23 addressing modes, barrel shift, and native 16×16 signed multiply / 32÷16 divide instructions. Its clock system integrates a programmable PLL (×1–×25), independent CPU/peripheral clock domains, and three oscillators: 4 MHz ceramic-resonator-compatible main clock, 32–100 kHz subsystem quartz clock, and 100 kHz/2 MHz internal RC oscillator for safe startup.

Peripheral integration includes two ISO16845-certified CAN controllers (32 message objects each, FIFO mode, loop-back self-test), seven full-duplex USARTs with LIN master/slave support, four I²C channels (400 kbps), and a flexible external bus interface with six chip selects, multiplexed address/data lines, and wait-state control - all managed through dedicated peripheral buses (CLKP1/CLKP2) decoupled from the CPU bus (CLKB).

Key Specifications

Pinout & Package

MB96F348RSAPMCR-GSE2 is housed in a 100-pin LQFP package (JEDEC MS-026AC, 14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad. Pin functions are defined across five I/O ports (P0–P4), two CAN transceiver interfaces (CAN0TX/CAN0RX, CAN1TX/CAN1RX), dual crystal inputs (X0/X1, X0A/X1A), analog supply pins (AVCC/AVSS/AVRH/AVRL), and dedicated external bus signals (AD0–AD15, A16–A23, CS0–CS5, RD/WR, ALE, ECLK).

FAQ

What is the maximum operating frequency and corresponding instruction cycle time?

The MB96F348RSAPMCR-GSE2 achieves a maximum CPU clock of 56 MHz using its internal PLL with a 4 MHz external resonator, resulting in a minimum instruction cycle time of 17.8 ns. This performance level is sustained across the full industrial temperature range (−40°C to +105°C) and supply voltage range (3.0 V to 5.5 V), verified per AC characteristics in datasheet Rev. *C Section 68.

Does this MCU support CAN FD or only classical CAN 2.0?

The MB96F348RSAPMCR-GSE2 implements two CAN 2.0A/B controllers compliant with ISO 11898-1:2015 and certified to ISO 16845 test suite for classical CAN only. It does not support CAN FD data rates, bit-rate switching, or extended data length frames. Its CAN modules operate up to 1 Mbit/s with 32 message objects per channel and programmable FIFO concatenation.

How is Flash memory protected against unauthorized read-out or accidental erase?

Flash security is enforced via a dedicated Flash Security feature that disables ROM read-out via serial programming interface after lock-bit programming. Erase protection is implemented per-sector: write/erase commands are rejected unless the target sector is explicitly unprotected via Memory Patch Unit (MPU) register writes. Low-voltage detection during erase prevents corruption if VCC drops below 2.7 V.

Can the external bus interface operate in 8-bit or 16-bit data width mode?

Yes - the external bus interface supports both 8-bit and 16-bit bidirectional data transfers, configurable via the BUSCON register. Address width extends to 24 bits (A0–A23), enabling access to up to 16 MB of external memory space. Chip select signals CS0–CS5 allow independent timing control per peripheral, with programmable wait states and multiplexed address/data lines (AD0–AD15).
