Following the automotive-grade dual-mode smart surface single-chip SOC TCAE11 and TCAE31, four more products from Shanghai Taisiwei have recently passed the AEC-Q100 reliability verification. These four products are highly integrated Signal chain SoC TCA025 and general MCU product TC01E, and 4-channel and 6-channel IO buffers TCIB04 and TCIB06.
With the development of automobile intelligence and electrification, the types and quantities of sensors used in automobiles have increased significantly. The new member of the Shanghai Taisi Micro MCU+ family, the car-level signal chain MCU product TCA025, is a multi-sensor developed in response to this market trend. Highly integrated single-chip solution.
TCA025 integrates ARM Cortex M0 low-power core. In addition to integrating 64 KB eFlash and 8KB SRAM, as well as standard SPI, UART, I2C, and LIN communication interfaces on the chip, the following characteristic peripherals have been developed for sensor applications:
High performance analog peripherals:
High-performance TIA transimpedance amplifier; Ib=50pA; Vos=3mV; can convert weak current signal into voltage signal, used for various photoelectric signal conversion and electrochemical catalytic reduction weak current detection;
2 OPAs and 2 comparators, which can be used for high-order analog filtering and signal comparison of detection signals;
2-stage PGA and 14bit SARADC are used for wide dynamic signal amplification and digitization to achieve high-precision signal detection and processing, and can also be used for monitoring the status of system voltage and current
VDAC and IDAC output for generation and dynamic adjustment of reference voltage or reference current signal;
9-way PWM pulse width modulation output, which can be used to control fans, stepper motors, LED dimming and other actuators.
Low power consumption:
Multiple low power consumption modes: Idle, Standby, Hibernate, Shutdown;
Deep Sleep power consumption <1uA;
Supports TinyWork® working mode, uA level average working current, which can maintain low power consumption during the continuous sampling process of the sensor.
Hardware encryption:
TCA025 also supports AES-128 and SHA-256 hardware encryption.
Automotive-grade MCUs have been in a state of tight supply in recent years. Another TC01E general-purpose MCU product from Tesilicon was born to solve this industry problem. TC01E can be widely used as a general-purpose product in the control of remote nodes that do not require high computing power, such as car lights, doors, tailgates, windows, sunroofs, rearview mirrors, and wipers.

High Current IO Buffers TCIB04 and TCIB06
The other two car-grade products TCIB04 and TCIB06 of Taisilicon are 4-channel and 6-channel high-current IO buffers. As the MCU process develops to a higher-level process, the cost of the wafer mask increases significantly. In order to reduce the chip area and reduce the cost, the IO drive capability of the advanced process MCU is significantly reduced, but some application scenarios require a higher drive capability of the IO port. , TCIB04 and TCIB06 have an IO fan-out capability of up to 24mA, which is a good supplement for applications that require high current drive capability.
