Microchip Technology introduced 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 devices feature a voltage regulator, windowed watchdog timer, battery monitor output, MCU, high Electromagnetic Compatibility (EMC) and Electrostatic Discharge (ESD) levels of more than 15 kV on the LIN bus and battery-voltage pins.
The new Microchip devices meet or exceed automotive manufacturer requirements such as Version 1.3 of the OEM Hardware Requirements for LIN, CAN and FlexRay Interfaces in Automotive Applications. In addition, the voltage regulator that is integrated on some of the devices has been specifically designed to operate in the automotive environment, and can withstand reverse battery conditions, +43V load dump transients and double-battery jump starts.
The new 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 — 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.
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 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. The MCP2050 SBC adds a watchdog timer, and is available in 14-pin SOIC and 20-pin QFN packages for $1.04 each.
