The PJM Light is a high performance Radio Frequency Identification (RFID) Chip based on ISO/IEC 18000-3
Mode 2 dedicated for object identification applications. Its command set is optimized for fast identification and
operation of large tag populations. High data rate commands are enabled through the use of Phase Jitter
Modulation (PJM) techniques. This high communication speed combined with eight reply channels in parallel and
highly reliable object detection enable high performance system setups. The implementation enables the
operation on tags which are closely stacked which includes systems for document management, supply chain
management and health care applications.
For ease of system migration, the PJM Light is fully compatible with the 10 kbit EEPROM SRF 66V10ST.
Applications working with the SRF 66V10ST which are using user memory not exceeding the SRF 66V01ST user
memory can switch to the PJM Light without system modifications.
On the other hand PJM Light applications with rising memory demands can be shifted to the SRF 66V10ST chip
taking into account the different command set.
The PJM Light complies with and is an enhancement of the ISO/IEC 18000-3 Mode 2 standard. This document
does not describe the functionality specified in the ISO standard. For system integration this data sheet has to be
read in combination with the relevant ISO standards, see ISO/IEC 18000-3 Mode 2.

Short Product Information
Analog Contactless Interface
– The Analog Contactless Interface comprises the voltage rectifier, voltage regulator and system clock
Operational Mode
– The memory access is controlled by commands sent to the PJM Light and the chip configuration such as
Memory Unit
– The Memory Unit consists of 80
Control Unit
– The Control Unit decodes and executes all commands. Additionally the control unit is responsible for the
recovery to supply the IC with appropriate power and clock. Additionally this block demodulates command
data and modulates reply data.
