Infineon Technologies CY9BF468NPMC-GNE2

Overview

CY9BF468NPMC-GNE2 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M4F microcontroller with FPU, 1024 KB MainFlash, 64 KB SRAM0, dual CAN 2.0B interfaces, and 24-channel 12-bit ADC-designed for motor control and industrial embedded systems requiring real-time precision, secure code execution, and multi-protocol connectivity.

For engineers reviewing the CY9BF468NPMC-GNE2 datasheet, CY9BF468NPMC-GNE2 pinout, CY9BF468NPMC-GNE2 application, or CY9BF468NPMC-GNE2 equivalent, key selection criteria include 160 MHz operation, hardware-accelerated CRC32/CCITT CRC16, dual QPRC for encoder feedback, DSTC-based zero-CPU-overhead peripheral transfers, and deep-standby RTC with VBAT support.

Technical Context

The CY9BF468NPMC-GNE2 implements a tightly coupled memory subsystem with three independent SRAM banks (SRAM0/SRAM1/SRAM2), enabling concurrent CPU and DMA access without bus contention. Its Flash Accelerator delivers zero-wait-state execution up to 72 MHz and maintains equivalent performance beyond via trace-buffer-assisted prefetching.

It integrates two independent CAN controllers compliant with ISO 11898-1:2015, each supporting 32 message buffers and 1 Mbps bit rate, alongside a dedicated Multi-function Timer unit with 6 output compare channels per unit-enabling synchronized PWM generation, dead-time insertion, and A/D trigger alignment for field-oriented motor control.

FAQ

What is the maximum operating frequency and does it require external cooling?

The CY9BF468NPMC-GNE2 operates at up to 160 MHz with its internal PLL and requires no active cooling under recommended operating conditions (T_A ≤ 85°C, V_CC = 3.3 V). Thermal design guidance specifies ≤10 cm² copper pour on Layer 2 beneath the 120-pin LQFP package for passive dissipation; junction temperature remains within spec at full load with standard 4-layer PCB layout.

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

This device supports only ISO 11898-1:2015-compliant classical CAN 2.0A/B (up to 1 Mbps) - not CAN FD. It features two independent CAN controllers, each with 32 message buffers, programmable bit timing, and built-in acceptance filtering. CAN FD functionality is absent in the FM4 CY9B460R series architecture per the Rev. *G datasheet.

How is the 32-byte backup register powered during main power loss?

The 32-byte backup register is powered exclusively by the VBAT supply pin, which must be connected to a standalone 2.7–5.5 V source (e.g., coin cell or supercapacitor). When VCC drops below LVD2 threshold, the device enters STOP or Deep Standby mode and retains register contents as long as VBAT ≥ 2.7 V - confirmed in Section 1.5 "VBAT" of the datasheet.

Is the Flash Accelerator enabled by default, or does it require firmware initialization?

The Flash Accelerator is enabled by default after reset and requires no firmware initialization to achieve zero-wait-state access up to 72 MHz. For frequencies above 72 MHz, the accelerator remains active and transparently manages prefetching and trace buffer usage; no user configuration is needed unless custom trace buffer allocation or scramble key loading is required.
