MPC852TVR66A - PowerQUICC MPU 66MHz 256-BGA | NXP
MPN： MPC852TVR66A ✗ 停產MPC852TVR66A 概覽
A microprocessor (MPU) such as the MPC852TVR66A combines a central processing unit, memory controllers, and system interfaces into a single integrated circuit. Within the broader taxonomy, it sits inside the power architecture microprocessor category, which itself belongs to the integrated circuits hierarchy alongside microcontrollers, DSPs, and ASSPs. The PowerQUICC family is NXP's lineage of Power Architecture-based communications MPUs, originally introduced to offload communications-intensive processing from embedded cores in networking equipment.
Key features of the MPC852TVR66A include a 32-bit data bus, on-chip Ethernet support, a flexible memory controller for DRAM and SRAM, and a peripheral set tailored to communications-controller designs. Operating at 66 MHz, the device targets mid-range line-card and access-equipment designs where deterministic performance and a mature tool chain matter more than raw clock speed. The 256-ball PBGA package supplies ample I/O while supporting surface-mount assembly with controlled-impedance signal routing.
Architecturally, the part leverages a single-issue, static Power Architecture core with separate instruction and data paths, tightly coupled to a communications processor module (CPM) that handles serial protocols. This dual-engine architecture allows the core to run control-plane code while the CPM services time-critical DMA channels, lowering overall CPU interrupt load in real-time designs.
Typical applications include Ethernet-to-Ethernet bridging on telecom line cards, WAN access routers, industrial serial gateways, and legacy communications controllers. It is also used in printer controllers and factory automation where deterministic serial-channel handling is required.
When designing with this device, verify that the available 66 MHz variant matches timing margins in the target system, confirm 256-PBGA PCB layout follows NXP's thermal and decoupling guidelines, and validate supply rail sequencing per the manufacturer datasheet. Note that this part is End of Life - check NXP's discontinuance notice for last-time-buy windows and recommended replacement families.

典型應用
MPC852TVR66A 適用於 6 應用s: Ethernet-to-Ethernet Line Card, WAN Access Router, Industrial Serial Gateway, Factory Automation Controller, Legacy Communications Controller, Printer and Imaging Controller.
Ethernet-to-Ethernet Line Card
The MPC852TVR66A's integrated CPM with on-chip Ethernet MAC support makes it a natural fit for Ethernet-to-Ethernet line-card designs in telecom access equipment. At 66 MHz, the Power Architecture core handles control-plane routing protocols while the CPM services DMA-driven packet forwarding with minimal CPU interrupt overhead. Compared to a discrete CPU + external MAC solution, the MPC852TVR66A reduces board area and BOM cost for high-port-density line cards. The 256-PBGA package supports the high-pin-count external memory bus required for buffering multiple Ethernet flows simultaneously.
推薦
WAN Access Router
In WAN access routers, the MPC852TVR66A provides deterministic serial-channel handling through its CPM, freeing the host core to run routing protocols and management stacks. The 66 MHz clock supports mid-range WAN interfaces where packet processing throughput matches T1/E1 and early Ethernet aggregation rates. The 256-PBGA footprint enables compact router mainboards with adequate thermal headroom at the 0-95C commercial temperature range. Designers pair it with external PHYs and TDM framer ICs to build complete access-router platforms.
推薦
Industrial Serial Gateway
Industrial serial gateways benefit from the MPC852TVR66A's robust CPM serial channel support, which handles multiple RS-232/RS-485 ports and protocol conversion with deterministic latency. The 66 MHz Power Architecture core runs gateway management software while the CPM services time-critical serial DMA without CPU intervention. The 0-95C operating range suits indoor industrial enclosures, though outdoor cabinets may require the wider-temp MPC8xx variants. Compared to microcontroller-only designs, the MPC852TVR66A delivers substantially higher throughput for multi-protocol gateway scenarios.
推薦
Factory Automation Controller
Factory automation controllers leverage the MPC852TVR66A's deterministic CPM-based serial handling to interface with fieldbus networks, motor drives, and PLC I/O. The 32-bit Power Architecture core executes real-time control loops while the CPM offloads fieldbus DMA, keeping interrupt latency predictable. The 256-PBGA package supports the address and data bus widths needed for external SRAM/DRAM buffers in motion-control loops. Note that the 0-95C commercial temperature range suits factory-floor enclosures but not outdoor or refrigerated environments.
推薦
Legacy Communications Controller
The MPC852TVR66A serves as a controller in legacy communications systems where deterministic serial-channel and DMA handling outweigh raw CPU clock speed. Per NXP's product page, the device 'provides superior performance over traditional architectures by offloading communications-intensive processing from the embedded core.' Maintenance and refresh designs for installed telecom equipment continue to specify the MPC852TVR66A, and the part's mature tool chain (NXP Design Alliance Program) simplifies long-life support.
推薦
Printer and Imaging Controller
Printer and imaging controllers historically adopted the MPC852TVR66A to drive print engines, scan subsystems, and network interfaces in parallel. The 66 MHz Power Architecture core runs page-rendering and control code, while the CPM handles scanner DMA and network packet flows. The 256-PBGA package provides the I/O and memory bandwidth needed to sustain high-resolution image pipelines. Designers can drop in the MPC852TVR50A for cost-sensitive printer SKUs that do not require peak throughput.

主要差異化特點
- 66 MHz headroom for timing-critical serial loops (對比MPC852TVR50A)
- Full MPC852T CPM feature set at 66 MHz (對比MPC870VR66)
- Lead-free compliant revision with same footprint (對比MPC852TVR66)
設計說明
The 256-ball PBGA requires a multilayer PCB stack-up with continuous ground planes beneath the BGA to control impedance on the external memory bus. Use microvia-in-pad escape on inner layers and place decoupling capacitors within 2 mm of the BGA balls. NXP's MPC852T datasheet recommends a minimum 4-layer board with 1 oz copper on power planes for adequate thermal spreading.
Estimated: at 66 MHz with 3.3 V core supply and typical 1.5 W active dissipation, the junction temperature rise is roughly 30-40C above ambient on a 256-PBGA with standard 1 sq inch copper pour. The 0-95C commercial operating range leaves adequate headroom for indoor telecom enclosures, but factory-cabinet designs above 55C ambient should verify with a thermal probe before committing to the layout.
Do not confuse the MPC852T with the MPC853T when sourcing substitutes - the 853T has an enhanced CPM with extra serial channels and a slightly different peripheral map. Also verify date codes: pre-RoHS revisions carry no 'A' suffix (e.g. MPC852TVR66), while 'A' suffix parts are the lead-free compliant version. Mixing date codes can cause assembly RoHS compliance failures.
合規資訊
RoHS status details were not surfaced in the verified web data. The 'A' suffix historically denotes the lead-free compliant revision - confirm against the NXP product page or MPC852T datasheet for the official RoHS statement.
