Frequently Asked Questions
Q1: What core architecture does PPC405EP‑3LB266C adopt?
A: It features a 32‑bit PowerPC 405 RISC core running at 266 MHz, manufactured on 0.18μm CMOS process.
Q2: What is the package of PPC405EP‑3LB266C?
A: 385‑ball E‑PBGA, 31 mm × 31 mm surface‑mount package. Package suffix “LB” stands for this E‑PBGA form factor.
Q3: Does PPC405EP‑3LB266C have built‑in Ethernet controllers?
A: Yes, dual 10/100Mbps Ethernet MACs with MII interface are integrated on‑chip.
Q4: What do the suffixes ‑3LB266C mean?
A: 3 = 266 MHz clock speed; LB = 385‑E‑PBGA package; C = commercial temperature grade (0°C~+70°C). Suffix‑I denotes industrial grade (-40°C~+85°C).
Q5: What are compatible alternative parts for PPC405EP‑3LB266C?
A: Similar alternatives: PPC405GP, PPC405GPr. Important: These are pin‑incompatible. You cannot swap them directly on existing PCB; hardware and firmware modifications are required.
Q6: What is the key difference between PPC405EP and PPC405GP?
A: PPC405EP integrates dual Ethernet MACs, while PPC405GP only has one Ethernet MAC. Their pin‑outs differ, direct PCB replacement is not supported.
Q7: Can different package suffixes of PPC405EP be used interchangeably?
A: No. Different suffixes correspond to different ball counts and package dimensions. They are not pin‑compatible and cannot be substituted without board redesign.
Q8: Does PPC405EP‑3LB266C support PCI 66MHz operation?
A: Yes, PCI Revision 2.2 supports up to 66MHz bus speed, subject to motherboard circuit configuration.
Q9: What is the typical power consumption of PPC405EP‑3LB266C?
A: Typical power dissipation is 0.72W at 266MHz operating frequency.
Q10: Is there an industrial‑temperature version of PPC405EP‑3LB266C?
A: Yes, the industrial variant uses suffix‑I, operating from -40°C to +85°C. The‑C suffix version is commercial grade only.
Q11: How do I get datasheet, pin‑out diagram or quotation?
A: Request datasheets, footprint drawings, stock status and bulk pricing via our Quick Inquiry form.
