  • Combines eXtreme low power consumption, high robustness and reliability
  • High integration options reduce cost, complexity and space:

Voltage regulator, windowed watchdog timer, battery-monitor output and a MCU

Microchip’s LIN Design Centre offers tools, software, reference designs and information

Microchip announces the expansion of 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).  These devices include high-integration options, such as a voltage regulator, windowed watchdog timer, battery-monitor output and a MCU.  Additionally, they feature high robustness, including high 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 that is integrated on some of the devices has also been specifically 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.

The new PIC16F1829LIN SiP incorporates an 8-bit Flash MCU, a voltage regulator and a LIN transceiver, in addition to peripherals such as a 10-bit ADC, comparators and timers; all in a 20-pin SSOP package.  This adds to Microchip’s wide range of eXtreme Low Power (XLP) 8- and 16-bit PIC® microcontrollers with integrated enhanced USART peripherals.  The enhanced USART peripheral enables 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 well suited to direct-battery applications and enable less drain on vehicle batteries.

Microchip provides a broad range of tools, software, reference designs and information to support development with its LIN portfolio, which can all be accessed from its online LIN Design Centre at http://www.microchip.com/get/STR3.  LIN tools available for purchase today include the LIN Serial

Analyser (APGDT001); PICDEM CAN-LIN 3 Demo Board (DM163015); ECAN/LIN PICtail Plus Daughter Board (AC164130); and PICkit 28-Pin LIN Demo Board (DM164130-3).  Available reference designs include the Window Lift With Anti Pinch (APGRD002) and Interior Ambient Light Module With LIN (APG000027).

All six of Microchip’s new LIN devices are available today for sampling and volume production.  The MCP2003A LIN transceiver is available in 8-pin SOIC and DFN packages; whilst the PIC16F1829LIN SiP is available in a 20-pin SSOP package.  The MCP2025 and MCP2021A SBCs, which integrate a LIN transceiver with a voltage regulator, are both available in 8-pin SOIC and DFN packages; and the MCP2022A SBC provides the same integration in 14-pin SOIC and TSSOP packages.  Finally, the MCP2050 SBC adds a watchdog timer, and is available in 14-pin SOIC and 20-pin QFN packages.
