New MCUs with core-independent peripherals enable functions for many applications

21-07-2015 | Microchip Technology | Semiconductors

Microchip has introduced two new 8-bit families that expand its growing
portfolio of innovative PIC MCUs with Core-Independent Peripherals (CIPs).

The 8-bit MCUs can now be used in a much broader range of applications, due
to the growing number of these intelligent, interconnected CIPs that combine
to perform functions autonomously, without the core.

Because these functions are deterministically and reliably performed in
hardware instead of software, CIPs enable system performance that is far
beyond typical 8-bit MCUs while simplifying the design experience and
reducing memory cost. Additionally, these two new families are available in
8 to 40-pin packages, reducing board space while serving a wide 1.8 to 5.5V
operating range. Both families offer the Peripheral Pin Select feature,
which enables flexible pin mapping and PCB routing to minimize EMI and
crosstalk. Example applications include consumer electronics, the Internet
of Things (IoT), wearable technology and safety-critical systems.

The four new members of the PIC16F1579 family are offered in 14 to 20-pin
packages with up to 28 KB of Flash and feature CIPs that enable functions in
a broad range of applications, such as LED lighting and motor control. They
are the 8-bit PIC MCUs with four 16-bit PWMs, each with independent timers
for flexible output and signal-generation functions, including edge,
centre-aligned and other output modes. System-communication functions are
supported via serial interfaces for LIN and DMX connectivity, while the
family's intelligent analogue integration enables signal and sensor
interface functions.

The first 10 members of the PIC16F18877 family are available in 8 to 40-pin
packages with up to 56 KB of Flash and feature CIPs that enable functions in
a broad range of applications, such as consumer electronics, IoT and
safety-critical systems. They are the first MCUs to integrate an ADC with
computation, which performs input and sensor interface functions such as
accumulation, averaging and low-pass filter calculations in hardware instead
of software, enabling the CPU to Sleep or execute other tasks. They are also
the first PIC16 MCUs to augment Microchip's eXtreme Low Power (XLP)
technology with the IDLE and DOZE modes for reduced active power
consumption. Additionally, they are the first 8-bit MCUs with Peripheral
Module Disable, which completely removes peripherals from the power rail and
clock tree for zero power leakage. Other integrated CIPs, such as the
Hardware Limit Timer, combine for the easy implementation of safety-critical
functions.

The Curiosity Development Board (DM164137) is available today, to enable
easy system design. The freely downloadable MPLAB Code Configurator
generates code with the click of a button. It provides a visual
representation of an MCU's peripherals, eliminating the need to read data
sheets. Additionally, it enables the easy setup of CIPs and provides
production-ready code, speeding the development efforts of both new and
experienced users. Microchip's MPLAB XC8 compiler and standard programmer /
debuggers are also available, says the company.
