MPC859DSLVR66A

The MPC859DSLVR66A is a single-core, 32-bit microprocessor from the MPC859 family, implementing the MPC8xx core architecture. With a 66 MHz core clock and an integrated communications-oriented peripheral set, this device targets embedded controller and networking/communications applications where integration and predictable performance are important.

Designed for surface-mount deployment in a 357-pin PBGA (25 × 25 mm) package and qualified for consumer applications, the MPC859DSLVR66A combines a PowerPC-based core, cache and MMU support, on-chip communications coprocessor resources, and multiple I/O interfaces to simplify board-level design.

Key Features

• Core — Single 32-bit MPC8xx core running at 66 MHz, implementing a PowerPC-based architecture suitable for embedded control and communications tasks.
• Cache and MMU — On-chip caches (4 KB instruction / 4 KB data for the MPC859DSL variant) and MMUs with 32-entry fully associative TLBs to support efficient code and data handling.
• Communications Coprocessor (CPM) — Integrated communications-focused coprocessor resources for protocol handling and peripheral control.
• Memory Controller — Integrated DRAM controller to interface with system memory subsystems.
• Ethernet Interfaces — Integrated Ethernet connectivity including one 10 Mbps interface and one 10/100 Mbps interface for networked applications.
• Peripheral Interfaces — Standard embedded interfaces including I2C for board-level control and sensor connectivity.
• Power — 3.3 V I/O voltage for compatibility with common embedded peripherals and interfaces.
• Package & Mounting — 357-pin PBGA (25 × 25 mm) package, surface-mount mounting type for compact board layouts; package case listed as 357-BBGA.
• Operating Range — Rated for an operating temperature range of 0 °C to 95 °C.
• Environmental — RoHS compliant.

Typical Applications

• Embedded Controllers — General-purpose embedded control where a single 32-bit core with MMU and cache is required for task handling and system management.
• Communications & Networking Equipment — Devices that require integrated Ethernet interfaces and communications coprocessor resources for protocol processing and connectivity.
• Consumer Electronics — Consumer-grade products that benefit from integrated peripherals, a compact PBGA package, and RoHS compliance.
• Industrial Controllers — Control systems and instrumentation that use DRAM-backed memory subsystems and standard interfaces such as I2C.

Unique Advantages

• Integrated Communications Resources: On-chip CPM and communications-focused coprocessor support reduce external component count for protocol handling and peripheral control.
• Balanced CPU and Memory Subsystem: Cache and MMU support (4 KB instruction / 4 KB data caches and 32-entry TLBs) deliver efficient code execution and virtual memory capabilities for embedded operating environments.
• Flexible Network Connectivity: Built-in Ethernet interfaces (one 10 Mbps and one 10/100 Mbps) simplify design of networked products without adding external PHYs for basic connectivity needs.
• Compact, Surface-Mount PBGA Package: 357-pin PBGA (25 × 25 mm) enables high-density board layouts while providing the pin count needed for integrated peripherals and memory interfaces.
• Industry-Standard I/O Voltage: 3.3 V I/O compatibility eases integration with common embedded peripherals and logic families.
• RoHS Compliant: Meets RoHS requirements for use in lead-free manufacturing environments.
