A3P125-VQ100I

The A3P125-VQ100I is a ProASIC3 field programmable gate array (FPGA) from Microchip Technology. It provides a moderate logic capacity with 3,072 logic elements and approximately 0.0369 Mbits (36,864 bits) of embedded RAM for implementing custom digital functions.

Designed as a surface-mount 100-pin TQFP device and graded for industrial use, the device supports a core supply range of 1.425 V to 1.575 V and an operating temperature range of −40 °C to 100 °C, making it suitable for a range of industrial and general-purpose embedded designs.

Key Features

• Logic Capacity — 3,072 logic elements (cells) providing room for moderate-complexity custom logic and finite-state designs.
• Gate Equivalent — 125,000 gates for sizing and partitioning custom digital functions.
• On‑Chip Memory — 36,864 bits of embedded RAM (approximately 0.0369 Mbits) to support buffering, small lookup tables, and state storage.
• I/O Count — 71 I/O pins to interface with peripherals, sensors, and external logic devices.
• Package and Mounting — 100-TQFP surface-mount package; supplier device package listed as 100‑VQFP (14×14) for PCB footprint reference.
• Power — Core voltage supply range of 1.425 V to 1.575 V to match targeted power domains.
• Industrial Temperature Range — Specified operation from −40 °C to 100 °C for deployment in temperature-demanding environments.
• Environmental Compliance — RoHS‑compliant construction.

Typical Applications

• Industrial Control: Implement custom control logic, interface multiplexing, and deterministic I/O handling within industrial automation systems operating across a wide temperature range.
• Communications Equipment: Provide protocol bridging and custom timing logic where a moderate number of I/Os and on‑chip memory are required.
• Instrumentation and Test Equipment: Enable custom signal processing blocks, trigger logic, and peripheral control in measurement and test platforms.

Unique Advantages

• Balanced Logic and I/O: 3,072 logic elements paired with 71 I/Os suit designs that need both internal logic and external interfacing without excessive board-level glue logic.
• Compact Surface‑Mount Package: 100‑pin TQFP footprint allows dense PCB implementations while retaining accessible I/O routing.
• Industrial‑Grade Operation: −40 °C to 100 °C rating supports deployment in temperature-variable environments common to industrial applications.
• On‑Chip RAM for Local Storage: 36,864 bits of embedded memory reduce dependency on external RAM for small buffers and LUT-based functions.
• Low‑Voltage Core: Narrow core voltage window (1.425 V–1.575 V) enables consistent power design and domain isolation on modern boards.
• RoHS Compliant: Environmentally compliant manufacturing supports regulatory and corporate sourcing requirements.
