The SLE5542 chip is a package chip commonly used in smart card production

I. SLE5542 chip card basic parameters.

1. 256-byte EEPROM organization

2. 32-bit protection memory composition

3. Three-byte user password, password error count: three times.

4. Temperature range: 0℃~70℃

5. At least 100,000 times erasure

6. Data retention period of at least 10 years

II. SLE5542 chip card production process.

1. Packaging material: PVC

2. Standard card size: 85.5×54×0.8(+/-0.04)mm, the card can be offset/silkscreen printed in advance at the factory, or printed with a small card printer.

3. Now the popular contact IC cards are mostly glossy cards, which can be added with magnetic stripe, convex code, hot stamping, barcode and other processes.

III. SLE5542 chip card security features

1. Each byte of the write protection area (the first 32 bytes) can be individually write protected. After write protection, the content cannot be changed (i.e., solidified data)

2. All data can be read until the password is properly checked. If necessary, the data can be encrypted appropriately.

3. After checking the password correctly, it can be written or modified.

4. The three-byte user password can be changed after checking correctly until the card is powered down.

5. The initial value of the password error counter is 3. If the password is checked incorrectly 1 time, it is reduced by 1 time. If the counter value is 0, the card will be automatically locked. Data can only be read, not change or check the password; if it is not zero, it can be restored to the initial value.

6. Byte addresses 0-5 and 6-7 have been written by the manufacturer before leaving the factory and cannot be changed.

At present, 5542 card is mainly applied to telecommunication card, IP card, smart card, IC card, membership card, electronic ticket, VIP card, medical, insurance, transportation, school, etc. Related products link:contact ic card induction ic card public ic card
