GD80960JA25

The GD80960JA25 is a single‑core, 32‑bit i960 microprocessor operating at 25 MHz with a 3.3 V I/O supply. It delivers deterministic instruction throughput with a one‑instruction‑per‑clock execution model and integrated system features targeted at embedded designs.

Designed for embedded microprocessor applications, the device integrates on‑chip memory, cache, timers and a high‑bandwidth bus to simplify system design while providing a compact 196‑ball BGA surface‑mount package and commercial‑grade temperature support.

Key Features

• Core & Performance i960 single‑core, 32‑bit architecture running at 25 MHz with one instruction per clock execution for predictable instruction throughput.
• Memory & Cache On‑chip program and data cache (JA variant program cache 2 KB, direct‑mapped data cache 1 KB) plus 1 KB of on‑chip data RAM for critical variable storage and faster single‑cycle access.
• Bus & Memory Interface 32‑bit multiplexed address/data bus with selectable 8/16/32‑bit bus widths and support for unaligned accesses and byte ordering selection to accommodate varied memory configurations.
• Interrupts & Timers High‑speed interrupt controller with multiple programmable priorities and maskable inputs, plus two independent 32‑bit on‑chip timers with clock prescaling (1, 2, 4 or 8) for precise event timing.
• System Integration On‑chip stack frame cache with multiple register sets available for rapid context save/restore; IEEE 1149.1 (JTAG) boundary‑scan compatibility for board‑level test and debug.
• IO & Compatibility 3.3 V supply with 5 V tolerant inputs and TTL‑compatible outputs, enabling compatibility with mixed‑voltage system interfaces.
• Power & Thermal Halt mode for reduced power draw and commercial operating temperature range of 0 °C to 100 °C.
• Package & Mounting 196‑ball mini plastic BGA (surface mount) package for compact board footprint and reliable soldered connections; RoHS compliant.

Typical Applications

• Embedded control systems — Single‑core 32‑bit processing and integrated timers make the device suitable for general embedded control and processing tasks.
• Industrial and commercial equipment — 3.3 V I/O, 5 V tolerant inputs and a commercial temperature range support deployment in a range of industrial and commercial products.
• Board‑level test and development — JTAG boundary‑scan compatibility and on‑chip debug/test support simplify development and manufacturing test flows.

Unique Advantages

• Deterministic execution: One‑instruction‑per‑clock core supports predictable timing for control and real‑time tasks.
• Integrated memory resources: On‑chip caches and 1 KB data RAM reduce external memory dependency and improve access latency for critical code and data.
• Flexible bus configuration: Selectable bus widths and support for unaligned accesses simplify interfacing to diverse memory and peripheral architectures.
• Robust system features: Programmable interrupt priorities, multiple timers and stack frame cache reduce software overhead for context management and event handling.
• Board‑level testability: IEEE 1149.1 (JTAG) boundary‑scan compatibility aids fault isolation and manufacturing test.
• Compact, RoHS‑compliant packaging: 196‑ball BGA surface‑mount package combines a small footprint with lead‑free compliancy for modern production requirements.
