The PIC16HV540 is a low-cost, high-performance, 8-bit, fully-static, EPROM based CMOS microcontroller. It is pin and software compatible with the PIC16C5X family of devices. It employs a RISC architecture with only 33 single word/ single cycle instructions. All instructions are single cycle except for program branches, which take two cycles. The PIC16HV540 delivers performance an order of magnitude higher than its competitors in the same price category. The 12-bit wide instructions are highly orthogonal resulting in 2:1 code compression over other 8-bit microcontrollers in its class. The easy to-use and easy-to-remember instruction set reduces development time significantly.The PIC16HV540 is the first One-Time-Programmable (OTP) microcontroller with an on-chip 3 volt and 5 volt regulator. This eliminates the need for an external regulator in many applications powered from 9 Volt or 12 Volt batteries or unregulated 6 volt, 9 volt or 12 volt mains adapters. The PIC16HV540 is ideally suited for applications that require very low standby current at high voltages. These typically require expensive low current regulators.The PIC16HV540 is equipped with special features that reduce system cost and power requirements. The Power On Reset (POR) and Device Reset Timer (DRT) eliminate the need for external reset circuitry. There are four oscillator configurations to choose from, including the power saving LP (Low Power) oscillator, cost saving RC oscillator, and XT and HS for crystal oscillators. Power saving SLEEP mode, Watchdog Timer and code protection features improve system cost, power and reliability.The UV erasable CERDIP packaged versions are ideal for code development, while the cost-effective OTP versions are suitable for production in any volume.
