160 MHz Cortex-M4F with FPU — control-loop headroom
The CY9BF466LPMC1-G-JNE2: The ARM Cortex-M4F core runs at 160 MHz, providing single-cycle MAC and hardware floating-point for motor-control FOC loops, inverter PWM generation, and sensor fusion algorithms without bit-banging in software. 544 KB of on-chip flash and 64 KB SRAM leave room for a real-time OS, communication stacks, and application buffers — the flash density suits firmware images that bundle bootloader, application, and calibration tables.
Peripheral set — fieldbus and analog front-end integration
Connectivity includes CANbus, I²C, LINbus, UART/USART, and CSIO — enough to bridge a CANopen fieldbus to local sensor clusters over I²C or LIN without an external protocol converter. Fifteen 12-bit ADC channels and two 10-bit DAC channels handle current/voltage sensing and analog output generation on a single chip — the ADC count supports three-phase current sensing plus auxiliary inputs. On-chip DMA, LVD, POR, PWM, and WDT peripherals reduce external component count — the PWM timers can drive a six-step inverter directly.
Package and board-fit — 64-LQFP 10x10 mm
Housed in a 64-LQFP with a 10x10 mm body and 0.5 mm pitch, the package routes out on a two-layer board for most I/O — the 48 available GPIOs leave headroom for parallel LCD or external memory interfaces.
Compliance and sourcing
ROHS3 compliant — no exemption-based restrictions for EU or UKCA market entry.
