Product details
Overview
CY91F587LAPMC-GTE1 from Infineon Technologies (formerly Cypress) is a 32-bit FR81S RISC microcontroller designed for automotive motor control systems. It operates at up to 128 MHz via PLL multiplication (4 MHz × 32), integrates 512+64 KB program flash, 48 KB main RAM, 8 KB backup RAM, and features dual CAN channels, FlexRay v2.1 controller, and IEEE 754-compliant FPU - deployed in electric power steering (EPS) and inverter control units.
For engineers reviewing the CY91F587LAPMC-GTE1 datasheet, CY91F587LAPMC-GTE1 pinout, CY91F587LAPMC-GTE1 application, or CY91F587LAPMC-GTE1 equivalent, key selection criteria include CAN/FlexRay coexistence, 128 MHz real-time deterministic execution, on-chip MPU with eight protection areas, and A/D conversion across 23 channels at 1 µs per sample - all critical for ASIL-B–aligned motor control firmware.
Technical Context
The CY91F587LAPMC-GTE1 implements the FR81S CPU core - a 5-stage pipelined 32-bit RISC architecture with 16 general-purpose registers, 16-bit fixed-length instructions, and hardware multiplier (3-cycle 16-bit signed multiply). It supports privilege/user mode operation with built-in MPU and IEEE 754 FPU for floating-point-intensive motor algorithms.
Peripheral integration includes dual CAN controllers (1 Mbps, 64-message buffers each), one FlexRay unit (128-message buffers, 8 KB message RAM), four multi-function serial interfaces (UART/CSIO/LIN/I²C), and three 12-bit A/D converters (23-channel total, 1 µs conversion time) - all synchronized to the same clock domain for deterministic timing in closed-loop control.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive motor control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TC375LPDxSAKXUMA1 (Infineon AURIX™ TC3xx) | Tri-core TriCore™ architecture, higher ASIL-D support, larger flash (2 MB), no integrated FlexRay | Targeted at full ADAS domain controllers; requires external FlexRay PHY and more complex safety certification | Select when ASIL-D compliance and multi-core lockstep are mandatory; not drop-in due to architectural divergence |

FAQ
What is the maximum operating frequency and how is it achieved?
The CY91F587LAPMC-GTE1 achieves a maximum operating frequency of 128 MHz using an on-chip PLL that multiplies a 4.0 MHz external crystal input by 32×. This configuration delivers a minimum instruction execution time of 7.81 ns. The PLL supports programmable multiplication factors from 1× to 32×, enabling flexible clock tree design while maintaining stability under automotive temperature ranges (−40°C to +125°C).
Does this MCU support functional safety standards like ISO 26262?
Yes - the CY91F587LAPMC-GTE1 includes hardware features aligned with ISO 26262 ASIL-B requirements: memory protection unit (MPU) with eight configurable regions, lockstep-capable watchdog timers (hardware and software), clock supervision with automatic CR oscillator fallback, and ECC-capable flash memory. While the device itself is not certified, its architecture enables ASIL-B–compliant system design when combined with appropriate software and hardware measures.
How many CAN and FlexRay interfaces does it integrate?
The CY91F587LAPMC-GTE1 integrates two independent CAN 2.0B controllers (CAN0 and CAN1), each supporting up to 1 Mbps and 64-message buffers, plus one FlexRay v2.1 controller with dual-channel capability (ch.A/ch.B), 128-message buffers, and 8 KB message RAM. These interfaces operate concurrently without shared resources, enabling mixed-criticality network topologies in modern E/E architectures.
What debug and programming interfaces are supported?
The MCU features an on-chip debug (OCD) unit compliant with JTAG and SWD protocols, supporting full real-time debugging, flash programming, and boundary-scan testing. It also supports in-system programming via CAN or UART bootloaders, and includes secure debug disable fuses for production firmware protection - all accessible through standard Infineon DAS tools and third-party IDEs like IAR Embedded Workbench.
