Atmel® offers all components needed to design a direct measuring sensor TPMS system (TPMS sensor modules and car module base stations). The TPMS product portfolio includes UHF receiver and transmitter ICs as well as highly integrated microcontrollers. All TPMS devices are suited for operating temperatures of up to 125°C and provide outstandingly low current consumption as required by TPMS system manufacturers to guarantee a module life time of 10 years.
Atmel®'s standard TPMS system solution includes low-power smart RF microtransmitter ICs and UHF ASK/FSK receivers. The TPMS standard solution is completed by an AVR® automotive microcontroller and LIN System Basis Chip with LIN Transceiver. This solution offers a high-integration level with low system costs. Atmel's POD system includes a 125 kHz built-in channel for waking up sensor modules in defined duty cycles, thus extending the battery life time. Such systems remarkably increase the flexibility of wheel initialization when changing tires by reprogramming the memory. Modes are adjustable from the dashboard.
Atmel's collection of smart drivers and bridges for DC-brush applications enable a myriad of electronic applications. As all drivers are manufactured using Atmel's 0.8-µm BCDMOS or SOI process technology, they supports operation up to 40V and can be optimized for applications in harsh environments.
Atmel's multi-half bridge drivers enable applications such as, electric mirrors, power windows, and electrical door locks. wiper etc. As these drivers are fully protected against overtemperature and undervoltage, the multi-half bridge drivers are an equally effective solution for climate control systems. Atmel's intelligent stepper motor drivers can be used for dynamic headlight adjustment solutions used in HID lighting systems.
Atmel's gate driver family is omnipresent in the modern automobile – found in seat module, sunroof, and wiper system solutions. And as Atmel's gate driver family are also available for high-temperature applications, they can be used for applications with ambient temperatures up to 150ºC such as turbo chargers, throttle control or exhaust recirculation systems.
Atmel®, having launched its first dedicated car access transmitter in 1997, recognizes the importance of security in the automotive area, and as such offers a range of car access solutions from immobilizers to full-duplex transceivers perfect for the prevention of automotive theft. Atmel's automotive safety portfolio also features the extremely secure Passive Entry Go (PEG) solutions.
Atmel provides all devices needed to design a complete car access system solution. Customers have the freedom to create their own dedicated designs using Atmel's low-power transmitter IC family, receiver IC family, and microcontroller family. Atmel recently extended their car access portfolio with a new receiver family, which offers higher integration, better sensitivity, and ultimately lower application costs.
Atmel not only provides devices for current car access systems, mainly built up with 2 separate links, but also supports next-generation systems with bi-directional RF link and dedicated LF wake-up channel for PEG systems.
Atmel car key ICs continue to provide a larger memory to serve as an interface between home applications (e.g., garage doors or alarm systems) and the car. A partnership with Atmel's existing AVR® 8-bit microcontrollers enables sophisticated RF systems with low power consumption and high computing power.
Atmel provides entire car radio system solutions (baseband and front ends), and supports upcoming highly integrated multi-standard broadcast radio solutions including AM/FM, HD Radio™, Digital Radio Mondiale™ (DRM), and the DAB derivatives Digital Multimedia Broadcasting (DMB) and DAB+.
Atmel® offers microcontrollers qualified to automotive requirements. It includes MARC4 4-bit devices, that have been used since many years, and AVR® 8-bit RISC Flash microcontrollers.
AVR 8-bit architecture has reached a high level of acceptance in many market segments for its performance, high code density and efficient development tool set. It is perfectly suited for many automotive applications. The range of devices made available to automotive already covers a variety of needs and is expanding rapidly.
Typical applications cover sensors and actuators control and in-vehicle networking with CAN (Controller Area Network) and LIN (Local Interconnect Network).
In addition to usual manufacturing and development plant qualifications (ISO-TS-16949 and QS-9000) automotive products are being qualified according to the AEC Q100 (Automotive Electronic Council) requirements, and a PPAP (Production Part Approval Process) document is made available for each product.
Atmel®'s automotive electronic efforts are not only focused on large complex electronic systems, but also on smaller independent applications. Building on Atmel's 20 years experience in automotive electronic designs, it offers a wide range of uniquely tailored stand-alone solutions.
