Product details
The SCH3227I-SZ by Microchip Technology pioneers ultra-low-power design in Embedded - Microcontrollers - Application Specific, specifically developed for energy harvesting applications. This application-specific microcontroller operates down to 0.8V supply voltage, enabling battery-less IoT deployments with multi-year operation.Tailored for I/O Controller scenarios, the device includes nanowatt-range wake-up receivers. The energy-aware architecture achieves 98% duty cycle reduction through predictive sleep scheduling.Built around 8042 Keyboard Controller technology, the CPU features subthreshold operation modes. The event-driven architecture consumes just 12 A/MHz during active processing.The ROM (2kB) organization supports shadow register banking for zero-energy state retention. The non-volatile memory maintains data at 0V supply through ferroelectric technology.The 256 x 8 memory implements ferroelectric retention for zero-power sleep. The memory controller includes energy-proportional access modes that scale with workload.Featuring IrDA, LPC, Parallel, Serial, UART connectivity, the device includes sub-1GHz RF frontends. Each communication peripheral implements adaptive impedance matching for energy-optimized transmission.With 40 ports, the GPIO subsystem features piezoelectric driver circuits. Configurable charge pumps enable direct energy harvesting from mechanical vibrations.Rated for -40°C ~ 85°C (TA) operation, the device uses zero-leakage transistors. The package design minimizes thermal gradients that could affect energy harvesting efficiency.The Surface Mount configuration supports flexible PCB installations. The ultra-thin package enables integration into wearable form factors.The 144-WFBGA option features transparent lids for solar cell integration. The package material selection maximizes light transmission to underlying photovoltaic layers.Available in 144-WFBGA (9x9) format, each unit is tested with actual energy harvesting sources. Production includes verification of cold-start capability.
