ST2378E8-bit Dual supply 1.71 V to 5.5 V level translator with I/O VCC +/-15 kV ESD protection | Integrated Circuits (ICs) | 1 | Active | The ST2378E device is an 8-bit, dual supply,bidirectional level translator with ±15 kV ESD protection on I/Os at VCCside. It is designed to interface data transfer between low voltage ASICs/PLDs and higher voltage systems. Externally applied voltage, VCCand VL, set logic levels at both sides with the range specified as 1.71 V ≤ VL≤ 5.5 V and VL≤ VCC≤ 5.5 V. For proper operation, VCCshould be set higher than VL.
Utilizing a transmission-gate-based design, this device allows bidirectional asynchronous data transfer, which means each channel is allowed to have either VCCto VLor VLto VCCdata transfer direction independently and no direction pin is required. The ST2378E device operates at a guaranteed data rate of 13 Mbps over the entire specified operating voltage range.
Among the other features, the OE pin allows disable mode operation whereby current consumption is reduced to less than 1 μA. |

ST2513.56 MHz short-range contactless memory chip with 512-bit EEPROM and anticollision fucntions | Evaluation Boards | 69 | Active | The ST25TB04K is a contactless memory, powered by an externally transmitted radio wave. It contains a 4096-bit user EEPROM. The memory is organized as 16 blocks of 32 bits. The ST25TB04K is accessed via the 13.56 MHz carrier. Incoming data are demodulated and decoded from the received amplitude shift keying (ASK) modulation signal and outgoing data are generated by load variation using bit phase shift keying (BPSK) coding of a 847 kHz sub-carrier. The received ASK wave is 10% modulated. The data transfer rate between the ST25TB04K and the reader is 106 kbit/s in both reception and emission modes.
The ST25TB04K follows the ISO 14443 - 2 Type B recommendation for the radio-frequency power and signal interface.
The ST25TB04K is specifically designed for short range applications that need re-usable products. The ST25TB04K includes an anticollision mechanism that allows it to detect and select tags present at the same time within range of the reader. The anticollision is based on a probabilistic scanning method using slot markers.
The ST25TB04K contact-less EEPROM can be randomly read and written in block mode (each block containing 32 bits). The instruction set includes the following nine commands:
The ST25TB04K memory is organized in three areas, as described in Table 1. The first area is a resettable OTP (one time programmable) area in which bits can only be switched from 1 to 0. Using a special command, it is possible to erase all bits of this area to 1. The second area provides two 32-bit binary counters which can only be decremented. The last area is the EEPROM memory. It is accessible by block of 32 bits and includes an auto-erase cycle during each Write_block command.
Die floor plan and physical options related to the die assembly are described in Figure 2.
For the option 1 of the die assembly, the CTUN (referenced in Table 2) can increase from 0.5pF to 1pF. The option 2 of the die assembly is showing a tripod which can be used for physical stability, having no impact on CTUN parameter. |
