| Microchip expands 20-pin PIC® microcontroller family | ||
| Microchip has announced two new 20-pin PIC® microcontrollers to further strengthen its 8-bit portfolio. The PIC16F631 provides a cost-effective migration from 8- and 14-pin devices, while the PIC16F677 offers affordable hardware I2C™ & SPI capability. The devices are fully compatible with Microchip’s range of PIC microcontrollers making them an excellent choice for cost reduction of existing 20-pin designs or upward migration of simpler designs to add more functionality. | |
Key Facts:
• Two New 20-pin PIC Microcontrollers • 4x4mm QFN Package option • Easy Code, Layout and Tools Migration from Existing 8, 14 and 20-pin Devices • PIC16F677 features 10-bit ADC, Hardware I2C™ & SPI | ||
The new devices are a compatible extension of the PIC16F685/687/689/690 series. The board layout, software, and tool suite can be completely re-used without modification giving engineers the freedom to design platform-based systems.
Both new microcontrollers feature nanoWatt Technology to minimise power consumption – including a Precision Internal Oscillator (operating from 31kHz up to 8MHz), an Ultra-low-power Wakeup function, an Enhanced low-power Watchdog Timer and an Enhanced low-power 16-bit Timer with Gate Control.
The key features of both devices include:
• Up to 3.5 Kbytes of Flash Program memory
• Up to 128 bytes of RAM
• Two Comparators with Set-Reset latch mode
• 0.6 Volt internal bandgap reference
• In-Circuit Serial Programming technology
• Brownout reset with software-control option
• Up to 18 I/O Pins
• 4x4 QFN package option
In addition, the PIC16F677 features:
• 12-channel, 10-bit ADC
• SPI and I2C support with Address Mask option
The new devices are supported by Microchip’s suite of development tools, including the free MPLAB® IDE (Integrated Development Environment), the low-cost PICkit™ 2 Starter Kit, and the MPLAB ICD 2 (In-Circuit Debugger).
The PIC16F631 and PIC16F677 microcontrollers are available in RoHS-compliant 20-pin PDIP, SOIC, SSOP and QFN packages.
