Product details
Overview
CY9BF468RBGL-GK7E1 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M4F microcontroller with 1024 KB Flash, 128 KB SRAM (64+32+32), dual CAN 2.0B interfaces, 24-channel 12-bit ADC, and operation up to 160 MHz. It integrates motor control timers, SD card interface, RTC, QPRC, and hardware CRC accelerator for embedded motor drives and industrial automation.
For engineers reviewing the CY9BF468RBGL-GK7E1 datasheet, CY9BF468RBGL-GK7E1 pinout, CY9BF468RBGL-GK7E1 application, or CY9BF468RBGL-GK7E1 equivalent, key selection criteria include dual CAN support at 1 Mbps, 160 MHz real-time execution with FPU and MPU, 12-bit ADC conversion in 0.5 μs, 5V-tolerant I/O on selected pins, and deep standby modes with RTC retention.
Technical Context
The CY9BF468RBGL-GK7E1 implements an Arm Cortex-M4F core (r0p1) with integrated FPU and Memory Protection Unit (MPU), enabling deterministic real-time control and memory isolation in safety-critical applications. Its dual CAN controllers comply fully with ISO 11898-1:2015 and support bit rates up to 1 Mbps with 32 message buffers per channel.
It features a multi-bus architecture: I-code/D-code buses for SRAM0 and system bus for SRAM1/SRAM2, plus external bus interface supporting SDRAM, NAND/NOR Flash, and SRAM with up to 256 MB address space. The DSTC (128-channel descriptor-based DMA) offloads CPU for high-throughput peripheral-to-memory transfers without intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RA6M4 Group (R7FA6M4AF3CFP) | 200 MHz Cortex-M4F, 1 MB Flash, 384 KB SRAM, single CAN FD, no QPRC, 16-bit ADC only | Lacks quadrature encoder interface and dual CAN; adds USB FS and TrustZone but no SD card interface | Select when CAN FD and security extensions outweigh need for motor position feedback and SD logging |
| S32K144 (S32K144HAT0MLHT) | 112 MHz Cortex-M4F, 512 KB Flash, 128 KB SRAM, dual CAN FD, 12-bit ADC, no SD interface, no QPRC | Automotive-qualified (AEC-Q100 Grade 1), includes ASIL-B safety features, but omits SD card and dedicated motor timers | Prefer for automotive ECU designs requiring functional safety certification over industrial motor control features |
Compared with RA6M4 and S32K144, the CY9BF468RBGL-GK7E1 delivers superior motor control integration (QPRC, DTIF, multi-channel PWM), SD card support for local data storage, and dual classical CAN-making it optimal for cost-sensitive industrial drives where encoder feedback and field-upgradeability are essential.

FAQ
What is the maximum operating temperature range for CY9BF468RBGL-GK7E1?
The CY9BF468RBGL-GK7E1 is specified for industrial temperature range: –40 °C to +85 °C ambient, validated per JEDEC JESD22-A104. It operates reliably under continuous 160 MHz execution with full peripheral activation within this range, provided PCB thermal design maintains junction temperature below 125 °C per datasheet Section 12.2.
Does CY9BF468RBGL-GK7E1 support secure boot or cryptographic acceleration?
No. The CY9BF468RBGL-GK7E1 does not include hardware cryptographic accelerators (AES, SHA, PKA) or immutable secure boot ROM. Code protection relies on Flash security bits and MPU-based memory isolation. For secure boot, external secure elements or software-based signature verification using its FPU and CRC accelerator are required.
Can the internal 4 MHz CR oscillator be used as the main system clock source?
Yes. The internal high-speed CR oscillator (4 MHz ±10%) can serve as the main clock source via the clock supervisor circuit. However, it lacks the stability needed for CAN bit timing or RTC accuracy; external crystals (4–48 MHz) or PLL-derived clocks are recommended for those functions per Section 12.3.2 of the datasheet.
Is there a development board available for CY9BF468RBGL-GK7E1?
Yes. Infineon offers the CY8CKIT-064S0S2-4343W kit, which uses the compatible CY8C6447FDI-S2D43 MCU and supports FM4 software libraries, middleware, and ModusToolbox™ IDE. While not pin-compatible, it shares identical peripheral IP, toolchain, and HAL - enabling rapid firmware prototyping before migrating to CY9BF468RBGL-GK7E1 in final hardware.
