Unlock Microcontroller PIC18F8390 Eeprom

We can Unlock Microcontroller PIC18F8390 Eeprom, please view the Microcontroller PIC18F8390 features for your reference:

· Memory Endurance: The Flash cells for program memory are rated to last for approximately a thousand erase/write cycles. Data retention without refresh is conservatively estimated to be greater than 100 years if Unlock Microcontroller.

· Extended Instruction Set: The PIC18F6390/6490/8390/8490 family introduces an optional extension to the PIC18 instruction set, which adds 8 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 when Unlock Microcontroller.

· 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. 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) after Unlock Microcontroller.

· 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, reduces code overhead after Unlock Microcontroller.

· Extended Watchdog Timer (WDT): This enhanced version incorporates a 16-bit prescaler, allowing a time-out range from 4 ms to over 10 minutes that is stable across operating voltage and temperature before Unlock Microcontroller.

Devices in the PIC18F6390/6490/8390/8490 family are available in 64-pin (PIC18F6X90) and 80-pin (PIC18F8X90) packages. Block diagrams for the two groups are shown in Figure 1-1 and Figure 1-2, respectively.

The devices are differentiated from each other in three ways:

1. I/O Ports: 7 bidirectional ports on 64-pin devices; 9 bidirectional ports on 80-pin devices if Unlock Microcontroller.

2. LCD Pixels: 128 (32 SEGs x 4 COMs) pixels can be driven by 64-pin devices; 192 (48 SEGs x 4 COMs) pixels can be driven by 80-pin devices if Unlock Microcontroller.

3. Flash Program Memory: 8 Kbytes for PIC18FX390 devices; 16 Kbytes for PIC18FX490. All other features for devices in this family are identical. These are summarized in Table 1-1. The pinouts for all devices are listed in Table 1-2 and Table 1-

3. Like all Microchip PIC18 devices, members of the PIC18F6390/6490/8390/8490 family are available as both standard and low-voltage devices. Standard devices with Flash memory, designated with an “F” in the part number (such as PIC18F6390), accommodate an operating VDD range of 4.2V to 5.5V. Low-voltage parts, designated by “LF” (such as PIC18LF6490), function over an extended VDD range of 2.0V to 5.5V when Unlock Microcontroller.
