P&E Microcomputer Systems ICD Interface Cable (CPU16 and CPU32) (BDM Interface)

The P&E Microcomputer Systems ICD Interface Cable enables in-circuit debugging and programming of Motorola CPU16 and CPU32 microcontrollers via Background Debug Mode (BDM). The cable bridges host PC parallel ports to target BDM interfaces, supporting E-Clock frequencies from 1.6 kHz to 50 MHz and target supply voltages from 1.8 V to 5.5 V.

– Technical Specifications

Interface & Connectors
• Host connection: DB25 Female (IBM PC parallel port)
• Target connection: 10-pin or 6-pin “Berg” connector
• Protocol: Background Debug Mode (BDM)

Electrical Performance
• Target supply range: 1.8 V to 5.5 V
• E-Clock frequency support: 1.6 kHz to 50 MHz (frequencies above 35 MHz not extensively tested)
• Power draw from target: <1 mA (USB-powered); <10 mA (USB-derived)
• Optional external power: 5 V center-negative supply jack

Host System Requirements
• Operating systems: DOS, Windows 2000, XP, 2003, Vista, 7, 8, 10
• Parallel port: IEEE1284 compliant; BIOS mode must be SPP, Normal, Standard, Output Only, Unidirectional, or AT

– Key Features

• Automatic BDM speed adjustment via P&E software
• Dual power options: target-derived or external 5 V supply
• Target-powered operation requires <1 mA from BDM header
• For HC12/HCS12 devices, IO_DELAY_CNT optimization formula included: `IO_DELAY_CNT = (120000000 / Fbus) – 1`

– Compatibility & Integration

Core support: Motorola CPU16, CPU32. Extended compatibility includes Motorola HSC08, HC12, 68MC9S12, and Freescale RS08, HCS08, HC12, HCS12, ColdFire V1, and PowerPC 5xx/8xx processors on select P&E BDM interface variants.
