EM4305 IC specifications
| Specification | Details |
|---|---|
| Semiconductor IC | EM4305 |
| Interface / protocol | LF; EM4469/EM4569 compatible command protocol |
| Operating frequency | 100–150 kHz; nominal 125 kHz application |
| Total EEPROM | 512 bits; 16 words of 32 bits |
| User data area | Words 5–13: 288 bits in the default message; additional uses defined by the memory map |
| Factory identifier | 32 bits |
| Access protection | 32 bit password for protected read and write operations |
| Data encoding | Manchester or biphase; configuration dependent |
| Memory protection | Word protection can prevent further writes |
Memory and protocol values describe the IC. Actual read performance depends on the finished antenna, enclosure, reader and operating environment.
512 bits is the total EEPROM, including UID, password, configuration and protection words. It is not 512 bits of unrestricted application storage.
Select data rate and modulation to match the installed reader. IC limits do not establish the temperature rating of the finished product.
Integration and qualification
Validate the modulation, bit rate and identifier format with the installed low frequency reader. NFC phones do not read 125 kHz credentials. For programmed formats, agree a sample identifier and confirm how the host system interprets it.
Agree the card construction, thickness, surface finish and printing process. Confirm that any slot, hole or magnetic stripe positioning is compatible with the antenna and personalization equipment.
Approve an encoded sample in the finished application before volume production. Define acceptance criteria for identification, memory access, printed data and repeated operation.
Define your production requirement.
