TI launches PLD programmable logic range
Texas Instruments has developed a range of integrated programmable logic devices (PLDs) that can be programmed at the engineer’s desk.
The TI PLD portfolio has up to 40 logic functions on a chip helps engineers go from concept to prototype in minutes without having to code by using a graphical design tool.
The devices are aimed at combining existing discrete logic designs in applications such as arbitration of multiple CAN buses in automotive designs. This can reduce board space by as much as 94%, says Tsedeniya Abraham, vice president and general manager of Interface at TI.
The PLDs use a one time programmable (OTP) non volatile memory (NVM) to implement the logic functions via look up tables. The NVM approach gives quiescent current less than 1µA and 50% less active power than similar devices on the market, helping to extend battery life in products such as power tools, battery packs and gaming controllers.
All the PLDs support general-purpose input/output, look-up tables, digital flip-flops, pipe delays, filters, and resistor-capacitor oscillators.
The TPLD1201 and TPLD1202 devices also integrate analog functions such as analog comparators, with internal selectable voltage reference options and hysteresis. The TPLD1202 offers additional elements such as Serial Peripheral Interface, I2C, a watchdog timer and a state machine.
The portfolio includes the industry’s smallest leaded package across all markets, measuring 2.1mm by 1.6mm with a 0.5mm pitch as well as automotive qualified AECQ100 parts with extended temperature range. The leaded package is 92% smaller than competing devices, supporting solderability at a fraction of the size.
TI’s automotive-grade PLDs are as much as 63% smaller than their closest competitors. The portfolio also offers quad flat no-lead (QFN) packaging options that enable automated optical inspection, ensuring safety and long-term system reliability.
“Engineers are increasingly considering programmable logic devices as a way to reduce design complexity and board space, simplify supply chain management, and accelerate their time to market,” said Abraham.
“Existing programmable logic devices are more complex than many applications require, involve programming expertise, or they come in limited packaging options. Our new programmable logic portfolio builds on TI’s 60 years of experience in logic design and offers small form factors in industry-standard packaging as small as 2.56mm2, low power consumption, AEC Q-100 qualification and a temperature range of -40°C to 125°C for applications including automotive, industrial and personal electronics.”
The TI PLD devices are configured with the InterConnect Studio tool which provides a graphical user interface. The devices can be programmed at the desk to speed up prototype development, and the devices can also be programmed at TI before shipping via the InterConnect tool for a secure supply chain.
