Microchip Develops OEM Automotive LIN/SAE MCP202X J2602 Transceivers

Microchip Technology Inc., a leading provider of microcontroller and analog semiconductors, announced the MCP2021 and MCP2022 (MCP202X) LIN/SAE J2602 transceivers. The new devices are 3rd party-LIN/J2602 approved, OEM approved, and AEC-Q100 certified to meet the stringent requirements of global automotive manufacturers worldwide. The transceivers include built-in voltage regulators and are compliant with the LIN Bus 2.0/2.1 and SAE J2602 standards, as well as the previous-generation LIN 1.X standards.

Microchip OEM-Compliant, Automotive-Certified LIN/SAE MCP2021 and MCP2022 J2602 TransceiversThe market momentum for LIN remains strong in all major product areas. According to the research firm Strategy Analytics*, LIN represents the second largest market segment in networked automotive applications, in terms of number of nodes. The MCP202X family represents Microchip’s second generation of LIN/SAE J2602, following the Company’s previous-generation MCP201 family.

With their built-in voltage regulator, the MCP202X transceivers reduce the number of external components needed, which increases system reliability and reduces overall design size. The transceivers’ proven robustness and world-class ESD performance enable reliable communication in even harsh environments, with minimal or no external components required. Additionally, the devices’ industry-leading low emissions eliminates the need for external shielding, which is of particular interest to noise-sensitive systems such as car radios, in-car entertainment systems, GPS navigation, mirrors, steering-wheel control and garage-door openers. Low power consumption in operational and standby modes (115 and 16 micro Amperes, respectively) makes the MCP202X transceivers suitable for non ignition-switched applications, and helps to extend battery life.

“The MCP202X transceivers’ proven robustness meets automotive manufacturers’ needs for reliable, cost-effective in-vehicle communication,” said Bryan Liddiard, vice president of marketing with Microchip Technology’s Analog & Interface Products Division. “The transceivers’ robustness, ESD performance and low power consumption, when combined with a microcontroller or digital signal controller, provide designers with maximum flexibility to incorporate new LIN/SAE J2602 features into their designs, in response to market requirements.”
