PRODUCTS EDITOR’S CHOICE MICROCHIP ADDS NEW PIC MCU FAMILIES


Microchip has released two new 8-bit families that expand its growing portfolio of innovative PIC MCUs with Core-Independent Peripherals (CIPs). 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 minimise 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 28KB 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 56KB 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 one of 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.

NEW SOC FOR HIGH-END PRINTERS


An integrated system on chip (SOC) has been developed by CSR that enables multifunction printers (MFPs) to seamlessly print documents from mobile devices, the cloud and traditional PCs and servers with high speed and excellent quality. The Quatro 5500 series is claimed to offer a low-cost alternative to traditional MFP solutions that combine a discrete CPU and a custom ASIC for printer-specific functions, and brings a significant reduction to the bill of material costs for MFP manufacturers. Each SOC in the series features dual ARM Cortex-A15 CPU cores, a companion Cortex-A7 core combined with a pair of CSR’s own 4-datapath SIMD DSP cores for image processing. Running the company’s IPS Universal Print Interpreter software, this series can deliver print processing speeds of over 70 pages per minute across all major print languages, as measured with the industry standard performance test file J11.ppt. By adding high speed interfaces including SuperSpeed USB 3.0, PCI Express and SATA, this series is able to efficiently meet the needs of a range of devices including monochrome laser printers, colour laser printers, MFPs and high-speed document scanners. The Quatro 5500 series combines a graphical LCD interface,


GPU, and high performance processor cores, with CSR’s wireless solutions and advanced printing software. This allows simple, secure, and convenient printing from any device. To allow printer manufacturers to get to market quickly, CSR offers a quick and easy software development environment. The CSR Inferno modular firmware platform provides developers with a single firmware base for the full range of Quatro SOCs, enabling the customisation of features to meet specific needs and efficiently build cost-effective controllers for a wide range of products. The Quatro programmable CPU, DSP and microcontroller cores also allow developers to implement their own unique features, image processing algorithms and mechanism controls using standard tools for faster software development.
