Transceivers for automotive applications
23 September 2008
OEM-compliant, automotive certified LIN/SAE J2602 transceivers available from Microchip.
The company has announced the launch of the MCP2021 and MCP2022 (MCP202X) LIN/SAE J2602 transceivers. Microchip claims that the devices are third party LIN/J2602 approved, OEM approved, and AEC-Q100 certified to meet the requirements of worldwide automotive manufacturers.
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.
Apparently, the market momentum for LIN remains strong in all major product areas, and according to 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 their previous generation MCP201 family.
The MCP202 transceivers with built-in voltage regulator reduce the number of external components needed. The transceivers’ robustness and ESD performance claim to enable reliable communication, even in harsh environments. Additionally, the devices’ low emissions eliminate the need for external shielding, which is of particular interest to noise-sensitive systems. Low power consumption in operational and standby modes (115µA and 16µA respectively), makes the MCP202X transceivers suitable for non ignition-switched applications, and helps extend battery life, according to the company.
Three low-cost development tools are available; the PICDEM CAN-LIN 3 demonstration board (DM163015), the ECAN/LIN PICtail Plus daughter board (AC164130), and the LIN serial analyser (APGDT001).
The MCP2021 transceiver is available in 8pin SOIC, PDIP, and 4mm x 4mm DFN packages. The MCP2022 transceiver is available in 14pin SOIC, TSSOP, and PDIP packages.
