Product details
Overview
CY9BF418TBGL-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 dead-time insertion logic - deployed in industrial motor drives and automotive body control modules.
For engineers reviewing the CY9BF418TBGL-GK7E1 datasheet, CY9BF418TBGL-GK7E1 pinout, CY9BF418TBGL-GK7E1 application, or CY9BF418TBGL-GK7E1 equivalent, this device supports real-time motor control, LIN 2.1 communication, hardware-accelerated CRC32/CCITT CRC16, and SWJ-DP debug with ETM trace - critical for deterministic embedded firmware development.
Technical Context
The CY9BF418TBGL-GK7E1 implements an Arm Cortex-M3 r2p1 core operating up to 144 MHz with MPU and NVIC supporting 48 peripheral interrupts across 16 priority levels. Its memory subsystem includes two independent SRAM banks (SRAM0/SRAM1, 64 KB each) connected to I/D-code and system buses respectively, enabling concurrent CPU and DMA access without contention.
Peripheral integration centers on deterministic real-time control: dual CAN controllers with 32 message buffers, 8-channel DMA with burst/block/demand transfer modes, and dedicated motor timing blocks - including QPRC with 16-bit position/revolution counters, base timers with PWM/PPG/PWC modes, and DTIF emergency stop interrupt capability.
Key Specifications

Key Features
| Feature | Design Value |
|---|---|
| Memory Protection Unit (MPU) | Enforces privilege-level memory access boundaries - prevents firmware corruption during ISR execution or peripheral register writes |
| Hardware CRC Accelerator | CCITT CRC16 and IEEE-802.3 CRC32 offload - reduces CPU cycles for firmware update integrity checks and CAN message CRC generation |
| Dual Watchdog Timers | Independent hardware (CR-oscillator clocked) and software watchdogs - ensures fail-safe reset even during deep STOP mode or clock failure |
| Port Relocate Function | Runtime remapping of peripheral I/O assignments - simplifies PCB layout reuse across variants without firmware changes |
| Low Voltage Detector (LVD) | Two-stage detection (LVD1 interrupt, LVD2 reset) at programmable thresholds - protects against brown-out induced state corruption in 2.7–5.5 V operation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit motor control microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F303RET6 | Arm Cortex-M4F core, 72 MHz max, 512 KB Flash, no native CAN FD, single CAN 2.0B, 16-channel 12-bit ADC (1.2 µs) | Lacks QPRC, dual CAN, and port relocate function - requires external logic for encoder interface and I/O flexibility | Prefer when FPU-based math acceleration is prioritized over motor-specific peripherals and CAN redundancy |
| RA6M3GFP | Arm Cortex-M4F core, 200 MHz, 1 MB Flash, dual CAN FD, 24-channel 12-bit ADC (0.9 µs), no QPRC hardware | Supports CAN FD but omits dedicated QPRC and DTIF interrupt - relies on software-based position decoding and fault injection | Choose when future-proofing for CAN FD migration outweighs need for hardware encoder counter and emergency stop logic |
Compared with STM32F303RET6 and RA6M3GFP, the CY9BF418TBGL-GK7E1 delivers superior deterministic motor control through integrated QPRC, dual CAN 2.0B with 32-message buffers, and hardware DTIF - reducing firmware complexity and improving worst-case interrupt latency by ≥3.2 µs in real-time loop closure.

FAQ
Does CY9BF418TBGL-GK7E1 support CAN FD?
No. The CY9BF418TBGL-GK7E1 implements two CAN 2.0B controllers compliant with ISO 11898-1:2003, supporting bit rates up to 1 Mbps. It does not include CAN FD protocol features such as flexible data-rate or extended payload length. CAN FD capability requires migration to Infineon's newer Traveo™ or AURIX™ families.
What is the maximum operating temperature range for this MCU?
The CY9BF418TBGL-GK7E1 is rated for industrial temperature range: –40 °C to +85 °C ambient, verified per JEDEC JESD22-A104. This applies to all operating modes including SLEEP, TIMER, and STOP - with thermal derating applied above 70 °C for continuous 144 MHz operation.
Is the Flash memory protected against unauthorized readout?
Yes. The device includes a security function that disables Flash readout via SWJ-DP interface when enabled. Protection is controlled by dedicated lock bits in the Flash configuration sector and persists across power cycles - preventing firmware extraction while allowing debug access only when unlocked.
Can the 176-pin LQFP package be used with standard reflow profiles?
Yes. The CY9BF418TBGL-GK7E1 in LQFP-176 complies with IPC/JEDEC J-STD-020D moisture sensitivity level 3 (MSL3) and supports standard lead-free reflow profiles with peak temperature ≤260 °C. Pre-bake is required if exposed to ambient >30 °C/60% RH for >168 hours prior to soldering.
