Overview
CY91F585ASGPMC1-GTE1 from Infineon Technologies (formerly Cypress) is a 32-bit FR81S RISC microcontroller designed for automotive motor control systems. It features a 128 MHz CPU core, 512+64 KB program flash, 48 KB main RAM, 1-channel CAN, 2-channel multifunction serial interface (UART/CSIO/LIN/I²C), and LQFP-64 package. It operates on single 5 V supply with internal 1.2 V regulation and supports ISO 17987 LIN v2.1 and ISO 11898 CAN.
For engineers reviewing the CY91F585ASGPMC1-GTE1 datasheet, CY91F585ASGPMC1-GTE1 pinout, CY91F585ASGPMC1-GTE1 application, or CY91F585ASGPMC1-GTE1 equivalent, key selection criteria include its 128 MHz FR81S core performance, 17-channel 12-bit ADC with 1 µs conversion time, FlexRay v2.1 controller with 128 message buffers, integrated FPU compliant with IEEE754, and automotive-grade low-power modes (Sleep/Stop/Watch).
Technical Context
The CY91F585ASGPMC1-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 integrates an IEEE754-compliant FPU and MPU with eight configurable protection areas supporting privilege/user mode access control.
Peripheral subsystems include a 12-bit successive-approximation ADC (17 channels, 1 µs conversion), dual 16-bit base timers configurable as PWM/PPG/reload units, 6-channel PPG, 7-channel output compare, and a FlexRay controller compliant with v2.1 supporting up to 128 message buffers and 8 KB message RAM - all synchronized via a unified clock system with PLL (×1–32) and trimmable CR oscillator.

FAQ
What is the maximum operating frequency and how is it achieved?
The CY91F585ASGPMC1-GTE1 achieves 128 MHz operation using its on-chip PLL with 32× multiplication of a 4 MHz external crystal. The FR81S core executes one 16-bit instruction per cycle at this frequency, delivering 128 MIPS performance. Minimum instruction execution time is 7.81 ns, verified under recommended operating conditions (VDD = 4.5–5.5 V, TA = −40 to +125 °C).
Does this MCU support functional safety standards like ISO 26262?
Yes - the CY91F585ASGPMC1-GTE1 is AEC-Q100 Grade 1 qualified (−40 to +125 °C) and includes hardware safety mechanisms: lockstep-capable MPU, dual watchdog timers (hardware and software), clock supervisor with quartz anomaly detection, and CRC generators for memory and communication. These features support ASIL-B decomposition in system-level ISO 26262 implementations.
How many CAN and FlexRay channels does it provide?
This part provides exactly one CAN 2.0B controller channel (up to 1 Mbps) and one FlexRay v2.1 controller unit supporting both Channel A and Channel B with 128 configurable message buffers and 8 KB message RAM. Unlike the AM-series variants, the AS-series (including CY91F585ASG) omits the second CAN channel to reduce pin count and cost while retaining full FlexRay capability.
Is the internal 100 kHz CR oscillator trimmable and usable in low-power modes?
Yes - the CR oscillator is factory-trimmed and supports user calibration via dedicated registers. It remains active in Sleep and Stop modes and serves as the clock source for the hardware watchdog timer and real-time counter functions. Oscillation stop during standby is enabled for this ASG variant, unlike AMG/AMH packages, reducing leakage current during deep sleep states.
