High Pin Count, Touchsensing, 8-bit MCUs
Supported Operating Systems: 8051
Supported 8-bit Architectures: 8-bit, 8051
The C8051F7xx family of high pin-count MCUs for cost-sensitive, high I/O embedded systems offers a robust, accurate, responsive and easy to configure touch sensing feature. With up to 54 general purpose I/O pins and a 25 MIPS 8051 CPU, the C8051F7xx family brings a high level of processing power and flexibility.
FEATURES & BENEFITS
- Fastest touch sense on-chip peripheral uses a capacitance- to-digital converter with 40 us acquisition time combined with 25 MIPS CPU enabling sophisticated cap sense, even when large arrays of touch sense elements are used.
- With up to 32 touch sensing inputs, featuring wakeon- touch, the MCU can be placed in a power saving mode and wake quickly upon touch to save overall system power in applications.
- A highly accurate 10-bit SAR ADC with on-chip voltage reference and temperature sensor provides best-in-class analog capability for measurement and control.
- Up to 54 general purpose I/Os are offered to be used as ADC voltage measurement inputs, capacitive touch-sense inputs and/or digital communications I/Os.
- A calibrated two percent oscillator with guaranteed accuracy over the full MCU voltage supply and temperature range eliminates the need for an external crystal.
