DALLAS, June 11, 2019 /PRNewswire/ -- Texas
Instruments (TI) (NASDAQ: TXN) today introduced an automotive
system basis chip that is the industry's first to integrate a
controller and transceiver for Controller Area Network with
Flexible Data Rate (CAN FD). Designed to meet the high-bandwidth
and data-rate flexibility needs of in-vehicle networks, the
TCAN4550-Q1 uses the Serial Peripheral Interface (SPI) bus of
almost any microcontroller to implement, with minimal hardware
changes, a CAN FD interface or increase the amount of CAN FD bus
ports in a system.
Previously, designers had to incorporate multiple discrete
components into their designs or change microcontrollers entirely
when upgrading to or expanding CAN FD functionality – an often
time-consuming and expensive process. With the TCAN4550-Q1 system
basis chip (SBC), designers can maintain their existing
microcontroller-based architecture and streamline CAN FD upgrade or
expansion in body electronics and lighting, advanced driver
assistance systems (ADAS) and automotive gateway designs. For
product details, see www.ti.com/TCAN4550-Q1-pr.
What is CAN FD?
The CAN FD communications protocol
builds on the original CAN bus standard (also known as "Classical
CAN") to help ensure that automotive microcontrollers and connected
systems can communicate effectively as the variety and speed of
data rates throughout in-vehicle networks continue to evolve. With
support for data rates up to 5 Mbps and payloads up to 64 bytes,
the CAN FD protocol empowers designers to move data faster in their
next-generation automotive applications.
Key features and benefits of TI's TCAN4550-Q1
- Reduced bill of materials (BOM) and system costs:
Designers can simplify their designs with the high integration of
the TCAN4550-Q1 – including integrated ±58-VDC bus fault
protection, watchdog timer and fail-safe modes – and its
cross-compatibility with the Classical CAN protocol.
- Easier bus expansion in automotive designs: Designers
can also use the chip to add more CAN FD buses via the existing SPI
port in an automotive system when the microcontroller has a limited
number of CAN FD ports. Typically this type of bus expansion can
require system redesign, which is not necessary when using the
TCAN4550-Q1.
- Small power design footprint: With an integrated 125-mA
low-dropout (LDO) linear regulator, the TCAN4550-Q1 can power
itself while also providing a 70-mA external output that can be
used to power sensors or additional components, which enables a
smaller power design footprint by reducing the need for external
power components.
- Reduced power consumption: The TCAN4550-Q1 helps
designers lower system power consumption when in standby mode
through wake and inhibit features.
- Increased maximum data rate: The new SBC enables faster
programmability of automotive software during vehicle assembly
through a maximum data rate of 8 Mbps, which exceeds the 5-Mbps
maximum data rate of the CAN FD protocol.
Save space while increasing system performance
This
new device joins TI's growing portfolio of SBCs that integrate CAN
FD, CAN, and Local Interconnect Network (LIN) transceivers and
power components into single-chip solutions, including the
TCAN4550-Q1 and TLIN1441-Q1. These highly integrated devices help
designers reduce their BOM, increase system performance and get
their designs to market faster, as compared to competing devices
with fewer integrated components. Designers can also pair TI SBCs
with TI C2000™ microcontrollers to quickly and easily expand the
amount of available bus ports while increasing overall system
functionality.
