3 Description

The TCAN241x-Q1 is a family of system basis chips

(SBC) that provide a control area network flexible

data rate capable (CAN FD) transceiver that meets

the physical layer requirements of ISO-11898:2-2024.

The CAN FD transceiver supports data rates up

to 8Mbps. The TCAN241x-Q1 integrates a buck

regulator (VCC1) that can output either 3.3V or 5V,

and provide up to 1A output current. The buck

regulator integrates spread spectrum modulation to

improve EMC performance. VCC2 LDO provides

5V output for loads up to 200mA. TCAN2411-Q1

supports Partial Networking by recognizing a selective

wakeup frame (WUF)

The TCAN241x-Q1 includes features such as LIMP,

four local wake inputs and four high side switches.

The high side switch can be on/off, 10-bit PWM or

timer controlled. Using the GFO pin, it is possible

to control an external CAN FD, LIN transceiver,

CAN SBC or LIN SBC. The WAKE pins can be

configured for static sensing, cyclic sensing (with

HSS4 pin) and pulse based for waking up. These

devices provide EEPROM to store specific device

configuration information thus avoiding extensive

reprogramming after power fluctuations.
