Reader Response Form
in the back of this data sheet to (480) 792-4150.
We welcome your feedback.
Most Current Data Sheet
To obtain the most up-to-date version of this data sheet, please register at our Worldwide Web site at:
http://www.microchip.com
You can determine the version of a data sheet by examining its literature number found on the bottom outside corner of any page.
The last character of the literature number is the version number, (e.g., DS30000A is version A of document DS30000).
Errata
An errata sheet, describing minor operational differences from the data sheet and recommended workarounds, may exist for current
devices. As device/documentation issues become known to us, we will publish an errata sheet. The errata will specify the revision
of silicon and revision of document to which it applies.
To determine if an errata sheet exists for a particular device, please check with one of the following:
• Microchip’s Worldwide Web site; http://www.microchip.com
• Your local Microchip sales office (see last page)
• The Microchip Corporate Literature Center; U.S. FAX: (480) 792-7277
When contacting a sales office or the literature center, please specify which device, revision of silicon and data sheet (include liter-
ature number) you are using.

GENERAL DESCRIPTION
The PIC16C55X are 18, 20 and 28-Pin EPROM-based
members of the versatile PIC16CXX family of low cost,
high
performance,
CMOS,
fully-static,
8-bit
microcontrollers.
All PIC
®
microcontrollers employ an advanced RISC
architecture. The PIC16C55X have enhanced core fea-
tures, eight-level deep stack, and multiple internal and
external interrupt sources. The separate instruction
and data buses of the Harvard architecture allow a 14-
bit wide instruction word with the separate 8-bit wide
data. The two-stage instruction pipeline allows all
instructions to execute in a single-cycle, except for pro-
gram branches (which require two cycles). A total of 35
instructions (reduced instruction set) are available.
Additionally, a large register set gives some of the
architectural innovations used to achieve a very high
performance.
PIC16C55X microcontrollers typically achieve a 2:1
code compression and a 4:1 speed improvement over
other 8-bit microcontrollers in their class.
The PIC16C554 has 80 bytes of RAM. The PIC16C557
and PIC16C558 have 128 bytes of RAM. The
PIC16C554 and PIC16C558 have 13 I/O pins and an 8-
bit timer/counter with an 8-bit programmable prescaler.
