PIC16F7X
FLASH Memory Programming Specification
1.0 PROGRAMMING THE PIC16F7X
The PIC16F7X is programmed using a serial method.
The Serial mode allows the PIC16F7X to be programmed while in the users’ system, allowing for increased design flexibility.
This programming specification applies to PIC16F7X devices in all packages.
1.1 Hardware Requirements
The PIC16F7X requires two programmable power supplies, one for VDD (2.0V to 5.5V) and the other for VPP of 12.75V to 13.25V.
Both supplies should have a minimum resolution of 0.25V.
编程和擦除 高电平要求 4.75 * 0.8 = 3.8V
供电电压小于 4.75V 只能读取和验证


PIC16F8X
EEPROM Memory Programming Specification
1.0 PROGRAMMING THE PIC16F8X
The PIC16F8X devices are programmed using a serial method. The Serial mode will allow these devices to be programmed while in the user’s system.
This allows for increased design flexibility. This programming specification applies to only the above devices in all packages.
1.1 Hardware Requirements
The PIC16F8X devices require one programmable power supply for VDD (4.5V to 5.5V) and a VPP of 12V to 14V.
Both supplies should have a minimum resolution of 0.25V.
高电平最小要求 4.5 * 0.8 = 3.6V
