Active 32-bit MCU for cost-sensitive control
The Infineon S6E1A12C0AGF20000 is an active-production ARM Cortex-M0+ microcontroller from the FM0+ S6E1A1 series, running at 40 MHz with 88 KB flash and 6 KB RAM on a 52-LQFP package. The 32-bit single-core processor targets entry-level control tasks where cost and power efficiency matter more than raw throughput — think appliance control, sensor hubs, or simple motor interfaces.
Peripheral set and connectivity
On-chip peripherals include DMA for memory transfers without CPU load, LVD for brown-out detection, POR for clean startup, PWM for motor or LED control, and a watchdog timer for system recovery. Serial connectivity covers CSIO, I²C, LINbus, and UART/USART — enough for sensor buses, display modules, or LIN-based automotive subnets without adding external interface chips. The 37 general-purpose I/O pins in the 52-LQFP package give reasonable headroom for control panels with a mix of inputs, outputs, and serial peripherals.
Package and rework considerations
The 52-LQFP package has a 10x10 mm body with 0.65 mm pitch — manageable with a standard hot-air rework station and fine-tipped iron for touch-up. No hidden pads, no BGA underfill.
Compliance and sourcing posture
ROHS3 compliant — no exemptions expiring, so it ships into EU and global markets without restriction.
