Microchip expands LIN portfolio
April 30, 2013 by John Day
Adds transceiver, System Basis Chip and System-in-Package devices
Microchip Technology Inc. has expanded its LIN portfolio with the LIN 2.1 and SAE J2602-2 compliant and low-power MCP2003A transceiver; MCP2021A, MCP2022A, MCP2025 and MCP2050 LIN System Basis Chips (SBCs), and PIC16F1829LIN System in Package (SiP).
The new devices include high integration options such as a voltage regulator, windowed watchdog timer, battery monitor output and an MCU. They also feature high robustness, including Electromagnetic Compatibility (EMC) and Electrostatic Discharge (ESD) levels of more than 15 kV on the LIN bus and battery-voltage pins, meeting or exceeding automotive manufacturer requirements such as Version 1.3 of the “OEM Hardware Requirements for LIN, CAN and FlexRay Interfaces in Automotive Applications.”
The voltage regulator integrated on some of the devices has been designed to operate in the automotive environment and can withstand reverse battery conditions, +43V load dump transients, and double-battery jump starts. This robustness enables reliable communication in harsh environments, and the high level of integration lowers cost and complexity while saving space.
System-in-Package (SiP) device
The PIC16F1829LIN SiP incorporates an 8-bit Flash MCU, a voltage regulator and a LIN transceiver, along with peripherals such as a 10-bit ADC, comparators and timers—in a 20-pin SSOP package. This adds to Microchip’s range of eXtreme Low Power (XLP) 8- and 16-bit PIC® microcontrollers with integrated Enhanced USART peripherals. The enhanced USART peripheral is said to enable easy connectivity to LIN physical layer transceivers and SBCs. Whether SiP or standalone solutions, Microchip’s XLP MCU sleep currents, which are as low as 9 nA, make them suitable for direct-battery applications and enable less drain on vehicle batteries.
Microchip provides tools, software, reference designs and information to support development with its LIN portfolio. All can be accessed from Microchip’s online LIN Design Center at http://www.microchip.com/get/STR3. LIN tools available for purchase today include the LIN Serial Analyzer (part # APGDT001), PICDEM™ CAN-LIN 3 Demo Board (part # DM163015), ECAN™/LIN PICtail™ Plus Daughter Board (part # AC164130) and PICkit™ 28-Pin LIN Demo Board (part # DM164130-3). Available reference designs include the Window Lift With Anti Pinch (part # APGRD002) and Interior Ambient Light Module With LIN (part # APG000027).
Pricing and availability
All six of Microchip’s new LIN devices are available today for sampling and volume production, and all of the following prices are listed in 5,000-unit quantities. The MCP2003A LIN transceiver is available in 8-pin SOIC and DFN packages for $0.60 each. The PIC16F1829LIN SiP is available in a 20-pin SSOP package for $1.75 each. The MCP2025 and MCP2021A SBCs integrate a LIN transceiver with a voltage regulator, and are both available in 8-pin SOIC and DFN packages, for $0.88 and $0.89 each, respectively. The MCP2022A SBC provides the same integration in 14-pin SOIC and TSSOP packages, for $1.01 each. Finally, the MCP2050 SBC adds a watchdog timer, and is available in 14-pin SOIC and 20-pin QFN packages for $1.04 each.
