Description

Yokogawa AF420 MegaNETIMPRESS Flash Programmer

Basic Identification

• Model: AF420 (MegaNETIMPRESS series)
• Type: Synchronous onboard serial flash programmer
• Application: Mass production programming for embedded MCUs
• Status: Legacy production tool (discontinued; replaced by newer DTS‑Insight models)
• Key Design: Modular base + up to 8 programmer units for parallel programming

Core Functions

• Multi‑Unit Parallel Programming: Up to 8 AF420 units on one base for high throughput
• Standalone & PC‑Controlled: Operate via front panel or remote (RS‑232/Ethernet)
• Programming Modes:
  • Blank check
  • Erase + blank check
  • Program (HEX/SREC)
  • Verify
  • Auto sequence (Erase → Program → Verify)
• Data Management: Save multiple programming environments; quick target switching
• In‑Circuit Support: Program MCUs mounted on PCBs (no chip removal)

Technical Specifications

Physical & Power

• Dimensions: 234.1 (W) × 100 (H) × 262.5 (D) mm
• Power: 100–240 VAC (universal input)
• Interfaces: RS‑232C, Ethernet (10BASE‑T), dedicated programming port
• Storage: PC Card (ATA Flash) for program files & settings

Compatibility

• Target MCUs: Fujitsu (Cypress) F²MC‑16LX, FR, FR60, MB91Fxxx 32‑bit families
• Control Modules: FF201 (16LX), FF205 (MB91F150), FF206 (MB91F360)
• File Formats: Intel HEX, Motorola S‑record

Key Features

• High‑Speed Programming: Faster than legacy AF220/AF210
• Synchronous Multi‑Write: All 8 units program simultaneously
• Production‑Ready: Integrates into automated test & programming lines
• Flexible Operation: Standalone (no PC) or remote control via AZ290 software
• Module Compatibility: Uses same FF‑series control modules as AF220

Typical System Configuration

1. Base Unit: Holds up to 8 AF420 programmer modules
2. Control Module (FF20x): Plugs into AF420 to match target MCU
3. Target Adapter: Connects to PCB for in‑circuit programming
4. PC (Optional): For remote control & file management (AZ290 software)
