It supports real-time embedded control in automotive body electronics and industrial motor drives.

For engineers reviewing the CY91F465PAPMC-GS-UJE1 datasheet, CY91F465PAPMC-GS-UJE1 pinout, CY91F465PAPMC-GS-UJE1 application, or CY91F465PAPMC-GS-UJE1 equivalent, key selection criteria include its QFP-176 package, dual-clock supervision (main 4 MHz / sub 32 kHz), C-CAN compliance at 1 Mbps, 10-bit ADC with 41 channels, and hardware bit-search module for RTOS optimization.

Technical Context

The CY91F465PAPMC-GS-UJE1 implements the FR60 CPU core with five-stage pipeline, 16-bit fixed-length instructions, and instruction-level multiplier supporting signed 32-bit multiplication in 5 cycles. It features Harvard architecture enabling simultaneous program/data access and full FR-family instruction compatibility.

Peripheral integration includes up to 4 C-CAN channels (128 message buffers), 12 LIN-USART channels (4 with FIFO), 4 I²C interfaces (400 kbps), and a 5-channel DMAC with 32-bit addressing and 8/16/32-bit transfer size selection - all operating under a unified clock domain with configurable PLL (×20).

Manufacturer

Infineon Technologies AG is a German semiconductor manufacturer specializing in power management, automotive MCUs, and security solutions, with global R&D and manufacturing infrastructure.

The CY91460P series was developed by Cypress (acquired by Infineon in 2020) to serve high-reliability embedded control applications demanding real-time determinism, multi-protocol connectivity (CAN/LIN/I²C), and extended temperature operation - particularly in automotive and industrial domains.

FAQ

What is the maximum operating frequency of the FR60 core in CY91F465PAPMC-GS-UJE1?

The FR60 core operates at a maximum frequency of 80 MHz (CLKB), achieved using the internal PLL configured with a ×20 multiplier on the 4 MHz main oscillator. This frequency is fully supported across the full −40°C to +125°C temperature range and verified in production testing per Infineon's automotive qualification standards.

Does CY91F465PAPMC-GS-UJE1 include an integrated LIN physical layer?

No, CY91F465PAPMC-GS-UJE1 integrates a LIN-USART controller (up to 12 channels, 4 with FIFO) but requires an external LIN transceiver (e.g., TLE7259-2GE) for physical layer compliance with LIN 2.2. The controller handles protocol framing, checksum, and break detection; the transceiver manages voltage level translation and bus protection.

How many CAN message buffers does the C-CAN controller support?

The C-CAN controller supports up to 32 transmission and 32 reception message buffers per channel, with up to 4 independent CAN channels. Buffers are organized in dedicated RAM areas and managed via message object registers - enabling concurrent handling of diagnostic, control, and status messages without CPU polling overhead.

Is the 10-bit ADC capable of simultaneous sampling across multiple channels?

No, the 10-bit successive approximation ADC performs sequential conversions only; it does not support true simultaneous sampling. However, its 1 μs minimum conversion time and hardware-triggered scan mode (via reload timer or external event) enable tightly timed multi-channel acquisition - achieving effective sample alignment within ±200 ns jitter across 41 channels.
