Once the functional requirements of the device are specified, some other decisions need to be
made. These include:
• Memory technology
• Operating voltage
• Operating temperature range
• Operating frequency
• Packaging
Microchip has a large number of options and option combinations, one of which should fulfill your
requirements.
Memory technology has no effect on the logical operation of a device. Due to the different pro-
cessing steps required, some electrical characteristics may vary between devices with the same
feature set/pinout but with different memory technologies. An example is the electrical character-
istic V
and a typical ROM device.
Each device has a variety of frequency ranges and packaging options available. Depending on
application and production requirements, the proper device options can be identified using the
information in the Product Selection System section at the end of each data sheet. When placing
orders, please use the “Product Identification System” at the back of the data sheet to specify the
correct part number.
When discussing the functionality of the device, the memory technology and the voltage range
do not matter. Microchip offers three program memory types. The memory type is designated in
the part number by the first letter(s) after the family affiliation designators.

Microchip focuses on Erasable Programmable Read Only Memory (EPROM) technology to give
the customers flexibility throughout their entire design cycle. With this technology Microchip
offers various packaging options as well as services.
Microchip offers a masked Read Only Memory (ROM) version of several of the highest volume
parts, thus giving customers a lower cost option for high volume, mature products.
ROM devices do not allow serialization information in the program memory space.
For information on submitting ROM code, please contact your local Microchip sales office.
These devices are electrically erasable, and can therefore be offered in a low cost plastic pack-
age. Being electrically erasable, these devices can be both erased and reprogrammed without
removal from the circuit. A device will have the same specifications whether it is used for proto-
type development, pilot programs, or production.
C, as in PIC16CXXX. These devices have EPROM type memory.
CR, as in PIC16CRXXX. These devices have ROM type memory.
F, as in PIC16FXXX. These devices have Flash type memory.
