MPC859DSLVR50A

The MPC859DSLVR50A is a single-chip microprocessor from the MPC8xx family featuring an embedded single-issue, 32‑bit PowerPC core running at 50 MHz. It combines CPU, on-chip memory management and caches, communications co‑processing, and peripheral controllers to serve a range of embedded and networking applications.

Designed for controller and communications systems, the device integrates Ethernet interfaces, DRAM controller support and serial/peripheral interfaces while operating from 3.3 V I/O and a consumer-grade temperature range of 0 °C to 95 °C.

Key Features

• Core Embedded single-issue, 32‑bit PowerPC core implemented in the MPC8xx family running at 50 MHz.
• Caches and MMU Two-way set-associative caches (4-Kbyte instruction cache and 4-Kbyte data cache for MPC859DSL) and an MMU with a 32-entry TLB to support virtual memory and efficient code/data handling.
• Communications Co-processor (CPM) On-chip communications processor module for handling serial and communications tasks, with enhanced ATM functionality noted for the MPC859 family.
• Ethernet Dual Ethernet capability with one 10 Mbps port and one 10/100 Mbps port to support mixed-speed network interfaces.
• Memory and Controllers Integrated DRAM controller support to interface with external memory for system and application data storage.
• Interfaces Standard peripheral interfaces including I2C and serial communications controlled by the CPM for device management and peripheral connectivity.
• Power and I/O 3.3 V I/O voltage compatibility for common embedded system designs.
• Package and Mounting Surface-mount 357-PBGA package (25 × 25 mm) for compact board-level integration.
• Operating Range Consumer-grade operating temperature range from 0 °C to 95 °C.
• RoHS Compliant Device is compliant with RoHS requirements.

Typical Applications

• Networking Equipment Use as a control and communications processor in routers, switches or access devices where dual Ethernet interfaces and CPM-managed serial ports are required.
• Telecommunications / ATM Systems Suitable for ATM-enabled functions and communication protocol handling leveraging the MPC859 family’s enhanced ATM capabilities.
• Embedded Controllers Integration of CPU, DRAM controller and peripheral interfaces makes it appropriate for industrial and commercial controller applications.
• Gateway and Interface Devices Acts as a bridge or protocol processor in gateway devices that require mixed-speed Ethernet connectivity and serial peripheral management.

Unique Advantages

• Integrated Communications Co-processor: The on-chip CPM offloads serial and communications tasks from the CPU, simplifying system design and reducing external component count.
• Dual Ethernet Support: One 10 Mbps and one 10/100 Mbps Ethernet interface enable flexible deployment in mixed-speed network environments.
• Compact BGA Package: 357-PBGA (25 × 25 mm) surface-mount package supports high-density PCB layouts while providing robust connectivity and thermal characteristics for embedded boards.
• Memory Subsystem: On-chip DRAM controller and cache/MMU features (including a 32-entry TLB) facilitate efficient memory management for real-time and communication workloads.
• Industry-Standard I/O Voltage: 3.3 V I/O compatibility aligns with common peripheral devices and board-level power architectures.
• Consumer Temperature Rating: Operates across 0 °C to 95 °C for a wide range of commercial and industrial indoor environments.
