PIC16F716
APPENDIX C:
This section discusses how to migrate from a baseline
device (i.e., PIC16C5X) to a mid-range device (i.e.,
PIC16F716).
The following are the list of modifications over the
PIC16C5X microcontroller family:
1.
2.
3.
4.
5.
6.
7.
8.
9.
10. Wake-up from Sleep through interrupt is added.
11. Two separate timers, Oscillator Start-up Timer
12. PORTB has weak pull-ups and interrupt-on-
13. T0CKI pin is also a port pin (RA4) now.
14. FSR is made a full eight bit register.
15. “In-circuit serial programming” is made possible.
16. PCON status register is added with a Power-on
17. Brown-out protection circuitry has been added.

Instruction word length is increased to 14-bits.
This allows larger page sizes both in program
memory (2K now as opposed to 512 before) and
register file (128 bytes now versus 32 bytes
before).
A PC high latch register (PCLATH) is added to
handle program memory paging. Bits PA2, PA1,
PA0 are removed from Status register.
Data memory paging is redefined slightly.
Status register is modified.
Four new instructions have been added:
RETURN, RETFIE, ADDLW, and SUBLW.
Two instructions TRIS and OPTION are being
phased out although they are kept for
compatibility with PIC16C5X.
OPTION_REG and TRIS registers are made
addressable.
Interrupt capability is added. Interrupt vector is
at 0004h.
Stack size is increased to 8 deep.
Reset vector is changed to 0000h.
Reset of all registers is revisited. Five different
Reset (and wake-up) types are recognized.
Registers are reset differently.
(OST) and Power-up Timer (PWRT) are
included for more reliable power-up. These

The user can program PIC16F716 devices
using only five pins: V

Preliminary
To convert code written for PIC16C5X to PIC16F716,
the user should take the following steps:
1.
2.
3.
4.

.
Note 1: This device has been designed to
Remove any program memory page select
operations (PA2, PA1, PA0 bits) for CALL, GOTO.
Revisit any computed jump operations (write to
PC or add to PC, etc.) to make sure page bits
are set properly under the new scheme.
Eliminate any data memory page switching.
Redefine data variables to reallocate them.
Verify all writes to Status, Option, and FSR
registers since these have changed.
Change Reset vector to 0000h
2: The user should verify that the device
perform to the parameters of its data
sheet. It has been tested to an electrical
specification designed to determine its
conformance with these parameters. Due
to process differences in the manufacture
of this device, this device may have differ-
ent performance characteristics than its
earlier version. These differences may
cause this device to perform differently in
your application than the earlier version of
this device.

values and/or the Oscillator mode may be
required.
