Product details
Overview
MB90F351ESPMC-GS-SPE1 from Infineon Technologies (formerly Cypress) is a 16-bit F2MC-16LX microcontroller with integrated FULL-CAN 2.0A/B interface, 64 KB Flash ROM, and 4 KB RAM, operating at up to 24 MHz with 42 ns instruction execution time. It features 15-channel 8/10-bit A/D converter (3 µs conversion), dual 16-bit free-run timers, 6-channel input capture, and 4-channel output compare - designed for automotive body control modules and industrial CAN node endpoints.
For engineers reviewing the MB90F351ESPMC-GS-SPE1 datasheet, MB90F351ESPMC-GS-SPE1 pinout, MB90F351ESPMC-GS-SPE1 application, or MB90F351ESPMC-GS-SPE1 equivalent, key selection criteria include CAN message buffer count (16), sub-clock support (X0A/X1A present), external bus disable status, Flash security absence, and LQFP-64 package compatibility with automotive-grade thermal range (−40°C to +125°C).
Technical Context
The MB90F351ESPMC-GS-SPE1 implements the F2MC-16LX CPU core with 24-bit internal addressing, supporting bit/byte/word/long-word data types and 23 addressing modes. Its PLL clock multiplier accepts 4 MHz crystal input and generates machine clocks from 4 MHz to 24 MHz, enabling deterministic 42 ns instruction timing under full load at 125°C.
It integrates a FULL-CAN controller compliant with ISO 11898-1:2003, featuring 16 prioritized message buffers, flexible acceptance filtering (full-bit compare/mask), automatic retransmission, and CAN wake-up capability. The peripheral set includes two LIN-UART channels (master/slave capable), one I²C interface (400 kbps), and an 8/10-bit ADC with external trigger support and selectable resolution per channel.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit automotive CAN microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MB90F352ESPMC-GS-SPE1 | 128 KB dual-bank Flash (concurrent read/write), Flash security lock, identical peripherals and pinout | Required for secure OTA firmware updates and runtime code patching in safety-critical systems | Select when cryptographic firmware protection or zero-downtime field updates are mandatory |
| SPC560B50L5 | 32-bit Power Architecture core, 512 KB Flash, integrated CAN FD, no LIN-UART, different toolchain and debug interface | Targeted at next-generation ASIL-B systems requiring CAN FD bandwidth and functional safety certification | Select only if migrating to ISO 11898-2:2016 CAN FD and AUTOSAR-compliant development flow |
Compared with MB90F351ESPMC-GS-SPE1, the MB90F352ES variant adds dual-bank Flash for safe firmware updates but shares identical CAN timing, ADC performance, and thermal specs; SPC560B50L5 offers higher compute throughput and CAN FD but requires full ecosystem requalification and lacks LIN-UART for legacy subsystem bridging.

FAQ
Does MB90F351ESPMC-GS-SPE1 support CAN FD?
No. This device implements FULL-CAN compliant with ISO 11898-1:2003 (CAN 2.0A/B), supporting data rates up to 1 Mbps with standard 11-bit identifiers. It lacks CAN FD's variable bit rate, extended data length, and CRC enhancements. For CAN FD, consider Infineon's AURIX™ TC3xx family or SPC56ELxx series.
Is the Flash memory on MB90F351ESPMC-GS-SPE1 protected against unauthorized readout?
No. Unlike MB90F352x variants, this part lacks Flash security lock functionality. Code protection requires external measures such as encrypted bootloader or secure element co-processing. The datasheet explicitly states Flash security is available only on MB90F352E(S) and MB90F352TE(S) devices.
Can MB90F351ESPMC-GS-SPE1 operate without an external crystal?
Yes - it supports internal RC oscillation for sub-clock mode (50 kHz), but the "S" suffix confirms X0A/X1A pins are present and intended for external 32.768 kHz crystal use. Main system clock still requires external 4 MHz crystal or ceramic resonator for PLL operation; internal RC is not rated for main clock accuracy or stability.
What is the maximum guaranteed ADC sampling rate across all 15 channels?
At 24 MHz machine clock, each 10-bit conversion takes 3 µs minimum (including sampling). With sequential channel scanning and no inter-channel delay, the theoretical maximum aggregate rate is ~333 kSPS (15 × 3 µs = 45 µs per full scan). Actual sustained rate depends on CPU overhead for result handling and interrupt latency.
