Additionally, Microchip offers a family of 8-bit MCUs which integrates fault-detecting hardware features to assist you in developing your safety-critical applications. This high level of integration makes these MCUs suitable for many applications like home appliances, industrial machinery, RPM indicators and power supplies. The Window Watchdog Timer (WWDT), Cyclic Redundancy Check with Memory Scan (CRC/SCAN) and Hardware Limit Timer (HLT) help ease implementation of safety standards or fail-safe features. In addition, the higher-memory products include additional peripherals to support control and power management applications. By eliminating code overhead and external components, these features help reduce design complexity and save costs, while also enabling faster time-to-market. Highlights ■ Cyclic Redundancy Check with Memory Scan (CRC/SCAN): Automatically calculates CRC checksum of Program/DataEE memory for non-volatile memory integrity. Additionally provides a general purpose 16-bit CRC for use with memory and communications data. Monitoring is done in hardware with no interruption to the CPU, reducing overall code. ■ Windowed Watchdog Timer (WWDT): System supervisory circuit that generates a reset when software timing anomalies are detected within a configurable critical window. Gives engineers the flexibility and ease to add monitoring to design. ■ 24-bit Signal Measurement Timer (SMT): Performs high-resolution measurements of any digital signal in hardware, resulting in more precise and accurate measurements. This can be used as a standard timer, ideal for speed control, range finding and RPM indicators. ■ Hardware Limit Timer (HLT): General purpose 8-bit timer/counter with hardware monitoring capabilities for missed periodic events and fault detection of external hardware. ■ Zero Cross Detect (ZCD): Detects high-voltage AC signals at the lowest crossing. Simplifies TRIAC and switching control, eliminating the need for additional components. ■ Complementary Waveform Generator (CWG): Provides non-overlapping complementary waveforms for various inputs including Comparators and PWM, while offering enhanced features like deadband control, auto shutdown, auto reset, phase control, blanking control. ■ Capture Compare and PWM (CCP): Includes a 10-bit PWM which can be utilized to implement a variety of motor control and lighting applications. Development Tools PICkit Low Pin Count Development Board (DM164130-9) ■ Development board for 8, 14, 20-pin 8-bit PIC MCU ■ Populated with PIC16F1829-I/P and ships with PIC18F14K22-I/P (20-pin) MCU ■ This board package contains assembled board with area for prototyping circuits and bare board as well ■ Software can be rewritten to accommodate new technologies Featured 8-bit MCUs with Safety-Critical Features Device PIC12(L)F1612 3.5 256 6 4/1 1 4 1 2/0 1 0 2/1 0 ü ü 0 – 0 0 PIC16(L)F1613 3.5 256 12 4/1 2 8 1 2/0 1 0 2/1 0 ü ü 0 – 0 0 www.microchip.com/8-bit |
