Microchip Technology Introduces PIC12LF1552 PIC Microcontroller

Microchip Technology PIC12LF1552 PIC microcontroller

Microchip Technology introduced the PIC12LF1552 PIC microcontroller. It features hardware I2C support, four channel 10-bit Analog-to-Digital Converter (ADC), and hardware Capacitive Voltage Divider (CVD) support for capacitive touch sensing. The PIC12LF1552 is the newest member of the PIC12/16F15XX 8-bit microcontroller (MCU) family. The Microchip PIC12LF1552 MCU is offered in 8-pin PDIP, SOIC, MSOP and 2x3x0.5 mm UDFN packages. It is available now for sampling and volume production.

The Microchip PIC12LF1552 microcontroller features 3.5 KB Flash program memory, 256 Bytes RAM, a 32 MHz internal oscillator, low-voltage operation from 1.8V to 3.6V, and low power consumption for active and sleep currents of 50 µA/MHz and 20 nA, respectively.

The hardware CVD enables a more efficient implementation of capacitive sensing for touch applications. The Core-Independent Peripheral includes additional control logic that enables automated sampling, which reduces software size and minimizes CPU usage. It also provides automatic control of guard-ring drive and a programmable sample-and-hold capacitance, to better match larger touch or proximity sensors.

The Microchip PIC12LF1552 PIC MCU is ideal for temperature-monitoring devices, small remote controls (garage doors and window blinds), smartphone buttons (input interfaces for Android and Windows 8 phones utilizing hardware CVD), room light control (switching and dimming, both taking advantage of hardware CVD), and coffeemakers (input interfaces and water-level monitoring.
