Core Independent Peripherals
Summary
Microchip is the leader in 8-bit microcontrollers
by continually investing and expanding upon the
PIC® microcontroller lineup. Emphasis is persistently
focused on reducing costs while developing products with
a strong mix of peripherals such as LCD drive, PWM, ADC,
comparators, timers and communication. Beyond standard
peripherals, Microchip is constantly bringing additional
value to PIC microcontrollers by developing unique and
exclusive peripherals. These unique peripherals allow
embedded engineers to simplify their designs and
create ever more innovative applications and products.
The following Core Independent Peripherals take 8-bit
MCU performance to a new level, while requiring no
processor overhead.

CLC (Congurable Logic Cell)
The CLC provides programmable
combinational and sequential
logic. It also enables on-chip
interconnection of peripherals
and I/O, thereby reducing external
components, saving code space,
and adding functionality.

NCO (Numerically Controlled Oscillator)
A programmable precision linear
frequency generator, ranging from
<1 Hz to 500 KHz+. The NCO
offers a step up in performance,
and a simplification in design,
for applications requiring precise
linear frequency control, such as:
Fluorescent Ballasts, Lighting Control,
Radio Tuning Circuitry, Class D Audio Amplifiers, etc.

HRPWM (High Resolution PWM)
A Patented solution using the CLC
and NCO to provide High (effective)
Resolution Pulse Width Modulation
at much higher switching frequencies
than achievable with standard PWMs.
This feature allows the use of smaller
inductors and capacitors, and has the
ability to induce jitter, lower cost, and
improve EMC performance.

COG (Complementary Output Generator)/
CWG(Complementary Waveform Generator)
The CWG provides a complementary
waveform with rising and falling edge
dead band control, enabling high
efficiency synchronous switching, with
no processor overhead. The CWG also
incorporates auto shutdown, auto
restart, and can directly interface with
other peripherals/external inputs.
The COG takes the CWG and improves its performance
with blanking and phase control.

PSMC (Programmable Switch Mode Controller)
The PSMC is a high performance
16-bit PWM with 6 configurable
outputs that can operate in multiple
modes. With a dedicated 64MHz
clock and the flexibility to interface to
external inputs as well as integrated
peripherals/clock sources, the PSMC
offers the highest level of advanced
PWM control and accuracy in an 8-bit MCU. The PSMC can
simplify the implementation of a wide array of applications
such as: motor control, lighting, and power supplies.
