Description
The Atmel® ATA5577M1330C-PPMY is a contactless read/write identification transponder (IDIC®) for applications in the
125kHz frequency band. It consists of a plastic brick which accommodates the read/write IDIC ATA5577M1330C. The
antenna comprises an inductor which in combination of the on-chip capacitor serves as power supply and bi-directional
communication interface.
The on-chip 363-bit EEPROM (11 blocks with 33 bits each) can be read and written block-wise from a base station (reader).
Two dedicated blocks are reserved for setting the IDIC operating modes. Another block may be used for a password to
prevent unauthorized writing.
Data is transmitted from the IDIC (uplink) using load modulation. This is achieved by damping the RF field with a resistive
load. The IC receives and decodes serial base station commands (downlink) which are encoded as 100% amplitudemodulated (OOK) pulse-interval-encoded bit streams.

General
The transponder consists of a plastic brick which accommodates the following components:
● Atmel® ATA5577M1330C Read/Write IDIC®
●
Note:
2.1
Coil with Ferrite Core
The antenna is implemented as a tuned inductor
Transponder Antenna
The antenna consists of a coil and an on-chip capacitor of Atmel ATA5577M1330C for tuning the circuit to the nominal
carrier frequency of 125kHz. The coil has a ferrite core for improving the distance of read, write and programming
operations.
2.2
Atmel ATA5577M1-PP Transponder Operation
The Atmel read/write IDIC ATA5577M1330C is part of the Atmel transponder ATA5577M1330C-PPMY. The data is
transmitted bi-directionally between the base station and the transponder. The transponder receives power via a single coil
from the RF signal generated by the base station. The single coil is connected to the chip and also serves as the IC’s bidirectional communication interface.
Data is transmitted by modulating the amplitude of the RF signal. The register contents are read by damping the coil voltage
using an internal load. Writing into registers occurs by interrupting the RF field in a specific way. The Atmel
ATA5577M1330C-PP transponder operates at a nominal frequency of 125kHz. There are varying bit rates and encoding
schemes. The on-chip 363-bit EEPROM (11 blocks with 33 bits each) can be read and written block-wise from a base station
(reader). The blocks can be protected against overwriting by using lock bits. Two blocks contain Atmel’s production
information and form a unique ID numbering system. Another block may contain a password to prevent unauthorized writing.
Two blocks are reserved for setting the IC's operating modes. See the Atmel ATA5577C datasheet for more detailed
information about Atmel ATA5577M1330C operating modes.

Configuration on Delivery
After Atmel® completes production, the transponder is configured as shown in Table 6-1. Unlike the ATA5577M1330C chip,
the AFE option setup (block 3, page 1) is adjusted to the transponder operating mode suitable for most applications.
All blocks in page 0 are not locked and may be re-programmed by the customer. Block 0 in page 0 is the configuration
register and is pre-programmed to the Atmel default operating mode: Manchester modulation with a data rate of RF/32. 2
data blocks (block 1 and block 2 in page 0) are transferred. The data of this 2 blocks is set to 0.
