14-Pin, 8-Bit CMOS Microcontroller

The PIC16C505 from Microchip Technology is a lowcost,
high-performance, 8-bit, fully static, EPROM/
ROM-based CMOS microcontroller. It employs a RISC
architecture with only 33 single word/single cycle
instructions. All instructions are single cycle (200 ms)
except for program branches, which take two cycles.
The PIC16C505 delivers performance an order of magnitude
higher than its competitors in the same price category.
The 12-bit wide instructions are highly
symmetrical resulting in a typical 2:1 code compression
over other 8-bit microcontrollers in its class. The easy
to use and easy to remember instruction set reduces
development time significantly.
The PIC16C505 product is equipped with special features
that reduce system cost and power requirements.
The Power-On Reset (POR) and Device Reset Timer
(DRT) eliminate the need for external reset circuitry.
There are five oscillator configurations to choose from,
including INTRC internal oscillator mode and the
power-saving LP (Low Power) oscillator mode. Power
saving SLEEP mode, Watchdog Timer and code
protection features improve system cost, power and
reliability.
The PIC16C505 is available in the cost-effective One-
Time-Programmable (OTP) version, which is suitable
for production in any volume. The customer can take
full advantage of Microchip’s price leadership in OTP
microcontrollers, while benefiting from the OTP’s
flexibility.
The PIC16C505 product is supported by a full-featured
macro assembler, a software simulator, an in-circuit
emulator, a ‘C’ compiler, a low-cost development programmer
and a full featured programmer. All the tools
are supported on IBMò PC and compatible machines.
