Functional Details

1. Key Functional Blocks

DC-DC Converter: Generates programmable 3.0V/5.0V CRDVCC for cards, supports step-up/step-down operation with minimal external components (inductor + capacitor)
Card Detector: Monitors card insertion/extraction via CRDDET pin, with 50μs debounce filter and interrupt output (INT)
Clock Generator: Selects synchronous (SYNCLK) or asynchronous (ASYCLKIN) clock source, with divide ratios (1/2/4) for CRDCLK
Level Translator: Bidirectional voltage translation between microcontroller (VBAT) and card (CRDVCC) for I/O, C4, C8, and RESET signals
Security Features: Overcurrent protection, undervoltage detection, active card pin pulldown, ESD protection, and controlled powerup/down sequencing

2. Operating Modes

Mode	Conditions	Key Function
Standby	CS=H, PWRON=L	Low-power card detection (30μA max current)
Programming	RDYMOD=L, CS falling edge	Configure CRDVCC (3V/5V) and clock settings
Active	CS=L, PWRON=L	Card presence detection, status polling
Transaction	CS=L, PWRON=H	Card power supply active, data transfer enabled
Idle	CS=H, PWRON=H	Card powered but no communication

3. Card Supply and Clock Programming (Table 3)

Application Guidelines

1. External Components

DC-DC Converter: Requires external inductor (L1=47μH typical) and CRDVCC filter capacitor (10μF typical)
Current Limitation: ILIM pin connects to PGND (0Ω) or external resistor to set peak coil current
Card Detection: CRDDET requires external pullup/pulldown resistor (depends on CRDCON setting)

2. Parallel Operation

Multiple MC33560DW devices can be connected in parallel via shared control/data buses
Each device uses a unique CS (chip select) pin for individual addressing
INVOUT pin daisy-chains ASYCLKIN across devices to minimize microcontroller load

3. Power-Saving Tips

Keep CS=H and PWRON=L for standby mode (30μA max current)
Disable ASYCLKIN in standby to avoid dynamic current
Leave pullup/pulldown pins in their default states (CS=H, RESET=L, SYNCLK=L)

4. Security and Protection

Card interface pins feature 4kV ESD protection (Human Body Model)
Overcurrent protection triggers shutdown after 160ms typical
Controlled powerup/down sequencing complies with ISO 7816-3
Active pulldown on card pins when not in operation
