The TPT24857 is an SD 3.0 spec-compliant memory card voltage-level translator with bidirectional control. It is designed to translate voltage between voltage 1.8 V to 3.0 V in the card side and 1.2 V to 1.8 V in the host side.

The BL25CM1A devices are Electrically Erasable Programmable Memory (EEPROM) organized as 131072 x 8 bits, accessed through the SPI bus.

The BL24C128A provides 131,072 bits of serial electrically erasable and programmable read-only memory (EEPROM), organized as 16,384 words of 8 bits each.

BL5372 is a low-power real-time clock circuit. It can communicate with the CPU in real time through the I2C two-wire interface circuit. It is mainly used in all systems that need to provide a time base. The chip can generate a variety of periodic interrupt pulses (the longest period can be up to 1 month) and has two time reporting systems. BL5372 has an internal integrated low-power regulated power supply, so it can keep the oscillator working normally at a very low power consumption under harsh environmental conditions (typical value: 400nA@3.6V).

The BL13232E consists of two drivers, two receivers, and a dual charge-pump circuit with ±12kV IEC 61000-4-2 Contact Discharge ESD protection.

The BL2555 Power Distribution Switch features internal current limiting to prevent damage to host devices due to faulty load conditions.

BL1590 is a 3~5.5V wide power supply, half-duplex RS-485 transceiver, which contains one driver and one receiver inside the chip. It can achieve error-free data transmission up to 16Mbps. BL1590 has a built-in failure protection circuit to ensure that the output of the receiver is in a logic high state when the receiver input is open or shorted.

The BL1521 is an 8-Channel Analog Multiplexer and Demultiplexer that is designed for 2.5V to 5.5V VCC operation. It has low on-resistance (40Ω TYP) and very low off-leakage current (1nA TYP). The BL1521 device handles both analog and digital signals.

The TPW4052 is a dual SP4T analog switch suitable for use in analog or digital multiplexer/demultiplexer applications. The switch features three digital select inputs (S0, S1), eight independent inputs/outputs (An, Bn), two common input/output (A, B), and a digital enable input (/E). When /E is HIGH, the switches are turned off.

The TPT3232E is IEC61000 ESD protected, 3.0V to 5.5V powered transceivers that meet the RS-232 standards for balanced communication. Each receiver converts TIA/RS-232 inputs to TTL/CMOS levels.
