2.0 PIC16C505 DEVICE VARIETIES
A variety of packaging options are available.
Depending on application and production
requirements, the proper device option can be
selected using the information in this section. When
placing orders, please use the PIC16C505 Product
Identification System at the back of this data sheet to
specify the correct part number.
2.1 One-Time-Programmable (OTP)
Devices
The availability of OTP devices is especially useful for
customers who need the flexibility of frequent code
updates or small volume applications.
The OTP devices, packaged in plastic packages, per-
mit the user to program them once. In addition to the
program memory, the configuration bits must also be
programmed.

2.2 Quick-Turnaround-Production (QTP)
Devices
Microchip offers a QTP Programming Service for
factory production orders. This service is made
available for users who choose not to program medium
to high quantity units and whose code patterns have
stabilized. The devices are identical to the OTP devices
but with all EPROM locations and fuse options already
programmed by the factory. Certain code and prototype
verification procedures do apply before production
shipments are available. Please contact your local
Microchip Technology sales office for more details.
2.3 Serialized Quick-Turnaround
Production (SQTPSM) Devices
Microchip offers a unique programming service, where
a few user-defined locations in each device are
programmed with different serial numbers. The serial
numbers may be random, pseudo-random or
sequential.
Serial programming allows each device to have a
unique number, which can serve as an entry-code,
password or ID number.

4.0 MEMORY ORGANIZATION
PIC16C505 memory is organized into program mem-
ory and data memory. For the PIC16C505, a paging
scheme is used. Program memory pages are
accessed using one STATUS register bit. Data mem-
ory banks are accessed using the File Select Register
(FSR).
4.1 Program Memory Organization
The PIC16C505 devices have a 12-bit Program
Counter (PC).
The 1K x 12 (0000h-03FFh) for the PIC16C505 are
physically implemented. Refer to Figure 4-1.
Accessing a location above this boundary will cause a
wrap-around within the first 1K x 12 space. The
effective reset vector is at 0000h, (see Figure 4-1).
Location 03FFh contains the internal clock oscillator
calibration value. This value should never be
overwritten.
