MC68306EH16BR2

The MC68306EH16BR2 is an embedded microprocessor from the MC68306 series featuring a single EC000 32‑bit core running at 16 MHz. It is designed for embedded systems that require a 32‑bit core with on‑chip DRAM control and serial communication support.

Packaged in a 132‑pin PQFP (24.13 × 24.13 mm) for surface‑mount assembly and specified for 5 V I/O, this device targets embedded applications where integration of core processing, memory interface, and serial I/O is important.

Key Features

• Core Single EC000 32‑bit core operating at 16 MHz, providing deterministic embedded processing capability.
• Memory Controllers Built‑in DRAM controller to support external dynamic RAM interfacing for data buffering and program storage.
• Power / I/O 5 V I/O voltage compatibility for use in standard 5 V embedded system environments.
• Interfaces Additional DUART interface included for dual asynchronous serial communications and peripheral connectivity.
• Graphics No graphics acceleration; suitable for control and communication tasks rather than GPU‑driven graphics.
• Package & Mounting 132‑pin PQFP (24.13 × 24.13 mm) supplier device package, supplied in Tape & Reel (TR) format and intended for surface‑mount assembly.

Typical Applications

• Embedded control systems — Use the EC000 32‑bit core and DRAM controller for control logic, data buffering, and program execution in embedded appliances and devices.
• Serial communications — DUART interface supports dual asynchronous serial links for device-to-device communications and peripheral control.
• Industrial and equipment controllers — 5 V I/O compatibility and surface‑mount PQFP package enable integration into industrial embedded boards and control modules.

Unique Advantages

• Integrated EC000 32‑bit core: Provides a single‑core 32‑bit processing element at 16 MHz for predictable embedded processing.
• On‑chip DRAM controller: Reduces external memory interface complexity by providing direct DRAM support.
• DUART serial support: Enables dual asynchronous serial channels for communications and peripheral interfacing without additional interface controllers.
• 5 V I/O compatibility: Matches conventional 5 V embedded system voltage levels for straightforward integration.
• Surface‑mount 132‑pin PQFP: High pin count in a defined 24.13 × 24.13 mm package supplied in Tape & Reel for automated assembly workflows.
