Memory Endurance: The Enhanced Flash cells for both program memory and data EEPROM are rated to last for many thousands of erase/write cycles – up to 100,000 for program memory and 1,000,000 for EEPROM. Data retention without refresh is conservatively estimated to be greater than 40 years.
Self-Programmability: These devices can write to their own program memory spaces under internal software control. By using a boot loader routine located in the protected Boot Block at the top of program memory, it becomes possible to create an application that can update itself in the field.
· Extended Instruction Set: The PIC18F1230/1330 family introduces an optional extension to the PIC18 instruction set, which adds eight new instructions and an Indexed Addressing mode. This extension, enabled as a device configuration option, has been specifically designed to optimize re-entrant application code originally developed in high-level languages, such as C.
· Power Control PWM Module: This module provides up to six modulated outputs for controlling half-bridge and full-bridge drivers. Other features include auto-shutdown on Fault detection and auto-restart to reactivate outputs once the condition has cleared.
· Enhanced Addressable USART: This serial communication module is capable of standard RS-232 operation and provides support for the LIN bus protocol. Other enhancements include automatic baud rate detection and a 16-bit Baud Rate Generator for improved resolution from Recover Chip PIC18F1330 Code.
When the microcontroller is using the internal oscillator block, the EUSART provides stable operation for applications that talk to the outside world without using an external crystal (or its accompanying power requirement).
· 10-Bit A/D Converter: This module incorporates programmable acquisition time, allowing for a channel to be selected and a conversion to be initiated without waiting for a sampling period and thus, reducing code overhead can help to Recover Chip PIC18F1330 Code.
· Extended Watchdog Timer (WDT): This enhanced version incorporates a 16-bit prescaler, allowing an extended time-out range that is stable across operating voltage and temperature.
See Section 22.0 “Electrical Characteristics” for time-out periods. Devices in the PIC18F1230/1330 family are available in 18-pin, 20-pin and 28-pin packages. The devices are differentiated from each other in one way:
1. Flash program memory (4 Kbytes for PIC18F1230, 8 Kbytes for PIC18F1330). All other features for devices in this family are identical. Like all Microchip PIC18 devices, members of the PIC18F1230/1330 family are available as both standard and low-voltage devices.
Standard devices with Enhanced Flash memory, designated with an “F” in the part number (such as PIC18F1330), accommodate an operating VDD range of 4.2V to 5.5V. Low-voltage parts, designated by “LF” (such as PIC18LF1330), function over an extended VDD range of 2.0V to 5.5V.
