PIC16F753/HV753
1.0 DEVICE OVERVIEW
This document includes the programming
specifications for the following devices:
2.0 PROGRAMMING THE
PIC16F753/HV753 DEVICES
The PIC16F753/HV753 devices are programmed using a
serial method. The Serial mode will allow these devices to
be programmed while in the user’s system. These
programming specifications apply to all of the above
devices in all packages.
2.1 Hardware Requirements
These devices require one power supply for VDD, see
Table 7-1 V
DD, and one for VPP, see Tabl e 7- 1 VIHH.
2.2 Program/Verify Mode
The Program/Verify mode for these devices allows
programming of user program memory, User ID
locations, Calibration Word and the Configuration
Word.

Note 1: In the PIC16F753/HV753, the programming high voltage is internally generated. To activate the Program/
Verify mode, voltage of V
IHH and a current of IIHH (see Table 7-1) need to be applied to MCLR input.
