Product details
Overview
CY9BF416SPMC-GK7E1 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller with 1 MB Flash, 128 KB SRAM, dual CAN 2.0B interfaces (up to 1 Mbps), 32-channel 12-bit ADC (1.0 µs conversion), and motor control peripherals including QPRC, multi-function timers, and PWM generators. It operates from 2.7 V to 5.5 V and supports real-time embedded control in industrial motor drives.
For engineers reviewing the CY9BF416SPMC-GK7E1 datasheet, CY9BF416SPMC-GK7E1 pinout, CY9BF416SPMC-GK7E1 application, or CY9BF416SPMC-GK7E1 equivalent, this device delivers deterministic real-time execution, on-chip memory protection (MPU), hardware CRC acceleration (CRC16/CRC32), and dual watchdog timers - critical for safety-aware motion control and automotive body electronics design.
Technical Context
The CY9BF416SPMC-GK7E1 implements an Arm Cortex-M3 r2p1 core running at up to 144 MHz with integrated NVIC (48 peripheral interrupts + 1 NMI), SysTick timer, and MPU for memory isolation. Its clock system includes five sources: main oscillator (4–48 MHz), sub-clock (32.768 kHz), two internal CR oscillators (4 MHz / 100 kHz), and main PLL.
Peripheral integration targets motor and industrial control: dual CAN controllers compliant with ISO 11898-1:2015, 8-channel multi-function serial interface (UART/CSIO/LIN/I²C), 16-channel base timer with PWM/PPG/reload modes, and 3-unit quadrature position/revolution counter (QPRC) with 16-bit position and revolution counters plus dual compare registers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M3 r2p1, up to 144 MHz - enables hard real-time task scheduling with <1 µs interrupt latency. |
| Flash Memory | 1 MB with Flash Accelerator - zero-wait-state access up to 72 MHz; maintains performance at higher frequencies via trace buffer-assisted prefetch. |
| SRAM | 128 KB total (64 KB SRAM0 + 64 KB SRAM1) - dual-bus architecture isolates instruction/data traffic from system bus contention. |
| CAN Interface | 2 channels, CAN 2.0A/B compliant, 1 Mbps max - supports distributed control networks with built-in 32-message FIFO buffers per channel. |
| A/D Converter | 32-channel, 12-bit SAR, 1.0 µs @ 5 V - supports high-speed current/voltage sampling for field-oriented control (FOC) loops. |
| Power Supply | 2.7 V to 5.5 V operation - enables direct interfacing with 3.3 V and 5 V industrial I/O without level-shifting. |
| Low-Power Modes | SLEEP, TIMER, STOP - STOP mode disables CPU/core clocks while retaining SRAM and register state; wake-up via QPRC or external interrupt. |
Pinout & Package
Package: 176-pin LQFP (24 × 24 mm, 0.5 mm pitch), RoHS-compliant, with 154 fast GPIOs - supports pin relocation for flexible peripheral mapping and 5 V-tolerant I/O on designated pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC / VSS | Power supply / Ground | Dual power domains: VCC1 (core/SRAM), VCC2 (I/O/ADC); decoupling required per datasheet layout guidelines. |
| XTAL / EXTAL | Main crystal oscillator input/output | Supports 4–48 MHz external crystal; essential for precise timing in CAN and UART communication. |
| OSC32K / OSC32KOUT | Sub-clock oscillator input/output | Drives 32.768 kHz watch counter for RTC and low-power wake-up intervals up to 64 s. |
| CAN0_TX / CAN0_RX | CAN controller 0 differential signal pair | Direct connection to external CAN transceiver; requires 120 Ω termination resistor on bus side. |
| AD00–AD31 | Analog input channels | 32 dedicated ADC inputs with configurable scan/priority modes; supports simultaneous sampling via hardware trigger. |
| MTIOC0A–MTIOC3B | Motor timer output capture/comparison | Hardware-generated dead-time insertion and complementary PWM outputs for 3-phase inverter gate drivers. |
Key Features
| Feature | Design Value |
|---|---|
| Memory Protection Unit (MPU) | Enforces privilege-level memory access boundaries - prevents firmware corruption during exception handling or peripheral ISR execution. |
| Hardware CRC Accelerator | Accelerates CCITT CRC16 and IEEE-802.3 CRC32 - offloads checksum computation from CPU for bootloader integrity verification and CAN message validation. |
| Quadrature Position Counter (QPRC) | 3 independent 16-bit position/revolution counters with A/B/Z input edge configuration - enables precise rotor position tracking without CPU polling. |
| Dual Watchdog Timers | Separate hardware (CR-oscillator-clocked) and software (CPU-clocked) watchdogs - ensures fail-safe reset even during deep sleep or clock failure. |
| Port Relocation Function | Runtime remapping of peripheral functions (e.g., UART, CAN, TIM) to alternate GPIO pins - simplifies PCB layout and avoids signal congestion. |
Applications
| Industrial Motor Drives | Automotive Body Control Modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F407VGT6 | 168 MHz Cortex-M4F, 1 MB Flash, no native CAN FD, single CAN 2.0B, no QPRC hardware block | Lacks dedicated QPRC and motor timer dead-time logic - requires software emulation for encoder counting and PWM safety features | Select when floating-point math or DSP extensions are prioritized over motor-specific peripherals. |
| RA6M4 Group (R7FA6M4AF3CFP) | 200 MHz Cortex-M33, 1 MB Flash, dual CAN FD, no hardware QPRC, 24-channel 12-bit ADC (0.9 µs) | Supports CAN FD but lacks QPRC and motor timer PWC/PPG modes - relies on GPT and software-based position interpolation | Select for future-proof CAN FD migration where encoder resolution is managed via external ASIC or FPGA. |
Compared with STM32F407VGT6 and RA6M4, CY9BF416SPMC-GK7E1 provides hardware-accelerated QPRC, motor-specific timers with dead-time insertion, and dual CAN 2.0B - delivering lower CPU load and higher determinism in motion control without external logic.

FAQ
Does CY9BF416SPMC-GK7E1 support CAN FD?
No. The device implements two CAN 2.0A/B controllers compliant with ISO 11898-1:2015, supporting bit rates up to 1 Mbps. It does not include CAN FD protocol features such as flexible data length or bit rate switching. CAN FD capability requires external protocol translation or migration to newer Infineon families like the AURIX™ TC3xx series.
What is the maximum operating temperature range for this MCU?
CY9BF416SPMC-GK7E1 is rated for industrial temperature range: –40 °C to +85 °C ambient. This is confirmed in Section 12.2 "Recommended Operating Conditions" of the datasheet (Document No. 002-04689 Rev. *F), with derating applied above 70 °C for sustained 144 MHz operation.
Is the Flash memory protected against unauthorized read-out?
Yes. The device includes Flash security functions: read-out protection (ROP) levels disable external debug access and Flash memory reads via SWJ-DP; write protection (WP) blocks prevent accidental or malicious reprogramming of designated Flash sectors. These are configured via dedicated Flash option bytes.
Can the 176-pin LQFP package be used with standard reflow profiles?
Yes. The package complies with JEDEC J-STD-020D moisture sensitivity level (MSL) 3 and supports standard lead-free reflow profiles (peak temperature ≤ 260 °C). Pre-bake is required only if exposed >168 hours at >30 °C/60% RH; full details are in Section 6.2 "Precautions for Package Mounting" of the datasheet.
