TPLD2001 概要
A programmable logic device is an integrated circuit whose logic function is defined by the user after manufacturing. In the TPLD family, InterConnect Studio is used to configure the non-volatile memory, either by emulating OTP memory or permanently programming the one-time programmable fuse. PLDs sit between standard fixed-function logic and large CPLDs/FPGAs, providing a compact, low-power way to integrate glue logic, timing, reset, power sequencing, and I/O expansion functions.
Key features include 18 GPIOs, 14 macrocells, and a configurable I2C/SPI port for system communication and in-system configuration. The 2/3/4-bit LUT macrocells allow flexible combinatorial logic; sequential blocks support timers, delays, and state machines. The wide 1.71V to 5.5V supply range permits operation from Li-ion batteries, 3.3V rails, or 5V industrial buses, and the -40°C to 125°C temperature range covers automotive and industrial environments.
The device's analog blocks provide voltage monitoring and reset generation, eliminating external supervisor ICs. Its low power and compact 20-VSSOP package make it suitable for space-constrained designs. Because logic functions are configured in the OTP memory and the same base part can be used across many designs, inventory can be consolidated. The selectable I2C/SPI port also allows integration into microcontroller-based systems for status readback or dynamic reconfiguration when the non-volatile logic is emulated.
Typical applications include timing delay generation, voltage monitoring and reset generation, power sequencing, I/O expansion, and glue logic consolidation in automotive body electronics, industrial sensors, and consumer devices. Designers can use InterConnect Studio to implement and simulate logic before programming.
When designing with TPLD2001, plan the OTP programming step during production and verify I/O assignments before programming, because OTP cannot be changed after the permanent fuse is blown.

主な用途
TPLD2001 の用途: 6 件s: Power Sequencing, Voltage Monitoring and Reset Generation, I/O Expansion, Timing Delay Generation, Automotive Body Electronics, Industrial Sensor Interface.
Power Sequencing
The TPLD2001 can implement multi-rail power sequencing with its configurable LUTs, timers, and sequential logic. Its 18 GPIOs provide enough outputs to drive enable pins of multiple DC-DC converters and LDOs, while its 1.71V to 5.5V supply voltage range allows direct operation from the monitored rails. In a typical system, the PLD is placed between the main PMIC enable signals and individual regulator EN pins, adding controlled delay and reset sequencing without an external sequencer IC. The wide -40°C to 125°C temperature range supports automotive and industrial power supplies.
おすすめ
Voltage Monitoring and Reset Generation
The TPLD2001 integrates analog blocks that can monitor supply voltages and generate a system reset when a rail falls outside an acceptable window. This eliminates a separate supervisor IC in many designs. The configurable 2-, 3-, and 4-bit LUTs allow custom reset timing, hysteresis, and system status combinations. Its wide supply range and automotive qualification make it suitable for powertrain, body control, and industrial control modules where reliable reset behavior is critical. Engineers can emulate the non-volatile memory in InterConnect Studio to validate reset thresholds before committing to OTP programming.
おすすめ
I/O Expansion
With 18 GPIOs, the TPLD2001 can act as a low-cost I/O expander for microcontrollers that need additional inputs, outputs, or keypad scanning. Its selectable I2C or SPI interface provides a compact connection to an MCU while the GPIOs handle switches, LEDs, or status signals. The 20-VSSOP package keeps PCB area small. Because the logic is configurable, the same physical part can be reused across different board variants with different I/O mapping, reducing inventory complexity. The 1.71V to 5.5V supply range allows direct interfacing with both 3.3V and 5V systems.
おすすめ
Timing Delay Generation
The TPLD2001 can generate precise timing delays using its internal sequential logic and configurable LUTs. It is well suited for delaying digital signals, debouncing switches, or generating strobe pulses in sensor interfaces. The wide supply voltage range and low power consumption allow it to run continuously in battery-powered equipment. Designers configure the delay in InterConnect Studio and can verify the behavior in emulation mode before programming OTP. This reduces the need for RC timers or discrete timer ICs, improving accuracy and reducing component count.
おすすめ
Automotive Body Electronics
The TPLD2001 is qualified for automotive applications and operates over -40°C to 125°C, making it suitable for body control modules, lighting control, and door modules. It can consolidate window switch logic, light sequencing, and wake-up signal conditioning into one small programmable device. The selectable I2C/SPI port enables communication with the central vehicle MCU or a CAN transceiver. By using the TPLD2001, designers reduce the number of discrete logic ICs on the PCB and simplify BOM management across multiple vehicle platforms. Verification of timing and reset behavior can be done in emulation mode before OTP programming.
おすすめ
Industrial Sensor Interface
The TPLD2001 can be used in industrial sensors for signal conditioning, alarm logic, and output control. Its 18 GPIOs allow interfacing with multiple sensor channels, while the internal combinatorial logic can implement window compare and threshold decisions. The wide supply range supports both 3.3V and 5V sensor boards, and the -40°C to 125°C temperature range covers harsh factory floor environments. The configurable I2C/SPI interface enables readback of sensor status to an MCU or PLC. This replaces several glue logic ICs and simplifies design changes when sensor logic thresholds are updated.

設計ノート
Place a 0.1uF ceramic capacitor close to the VCC pin and a 1uF bulk capacitor on the same rail to keep the supply impedance low. TPLD2001 operates from 1.71V to 5.5V, so ensure that transient excursions on the supply do not exceed the absolute maximum ratings. If the device is driving multiple GPIO loads, include a small series resistor on outputs to limit inrush current.
Keep I2C/SPI traces short and balanced to minimize noise. For I2C, place appropriate pull-up resistors (typically 2.2k to 10k) to VCC. For SPI, match trace lengths between the PLD and host MCU. Since the 20-VSSOP has a small pitch, use thermal relief pads if hand assembly is expected, and follow TI layout guidance for the exposed thermal pad if present.
The TPLD2001 uses one-time programmable (OTP) memory. Before committing the OTP fuse, always use InterConnect Studio emulation mode to validate the logic, I/O mapping, and timing. Once OTP is blown, the programmable logic cannot be changed. Also verify the pinout from the official TI datasheet before PCB design, because the verified web data for this product page does not include the complete pin table.
