Legislation and Compliance
RoHS Certificate of Compliance
EU Directives 2011/65/EU and 2015/863 restrict the use of the 10 substances below in the manufacture of specified types of electrical equipment.
Whilst this restriction does not legally apply to components, it is recognised that component “compliance” is relevant to many customers.
RS definition of RoHS Compliance:
- The product does not contain any of the restricted substances in concentrations and applications banned by the Directive,
- and for components, the product is capable of being worked on at the higher temperatures required by lead–free soldering
The restricted substances and maximum allowed concentrations in the homogenous material are, by weight:
Substance | Concentration |
Lead | 0.1% |
Mercury | 0.1% |
PBB (Polybrominated Biphenyls) | 0.1% |
PBDE ( Polybrominated Diphenyl Ethers) | 0.1% |
Hexavalent Chromium | 0.1% |
Cadmium | 0.01% |
DEHP (Bis (2-Ethylhexl) phthalate) | 0.1% |
BBP (Benzyl butyl phthalate) | 0.1% |
DBP (Dibutyl phthalate) | 0.1% |
DIBP (Diisobutyl phthalate) | 0.1% |
The supplier of the item listed below has informed RS Components that the product is "RoHS Compliant".
RS Components has taken all reasonable steps to confirm this statement. Information relates only to products sold on or after the date of this certificate.

Product Details
EEPROM Serial Access - Microchip
25AA512/25LC512 SPI Serial EEPROM
Microchip’s 25AA512/25LC512 family of devices are 32 Kbit SPI Serial EEPROMs available in a variety of package, temperature and power supply variants. Featured are Page, Sector and Chip Erase functions typically associated with Flash based products.
The Serial Peripheral Interface (SPI) is utilised to provide the required Clock Input (SCK), Data In (SI) and Data Out (SO) signals. The operation of these devices can be paused via a Hold pin (HOLD) which causes inputs to be ignored with the exception higher priority interrupts defined via the Chip Select (CS) pin.
Features
20 MHz maximum Clock Speed
Byte and Page-level Write Operations (5 ms maximum): No page or sector erase required
128-byte Page
Maximum Write Current: 5 mA at 5.5V, 20 MHz
Read Current: 10 mA at 5.5V, 20 MHz
Standby Current: 1μA at 2.5V (Deep power-down)
Electronic Signature for Device ID
Self-Timed Erase and Write Cycles: Page Erase (5 ms typical), Sector Erase (10 ms/sector, typical) and Bulk Erase (10 ms, typical)
Sector Write Protection (16K byte/sector): Protect none, 1/4, 1/2 or all of array
Built-In Write Protection: Power-on/off data protection circuitry, Write enable latch Write-protect pin
Endurance: 1 Million erase/write cycles
Data Retention: >200 years
ESD Protection: >4000V
