Technical Reference
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
FT230X, FT231X, FT234XD - Full Speed USB to UART, FTDI Chip
The FTDI Chip FT230X and FT234XD are Ful Speed USB to basic serial UART interface devices. The FT231X is a Full Speed USB to Full Handshake UART interface.
They have a fully integrated MTP memory and an integrated clock circuit which requires no external crystal which helps to reduce external component count.
Capable of operating up to 3 MBaud, with low power consumption (8 mA), all USB to UART devices operate efficiently with USB host controllers. They use as little bandwidth as possible.
The FT230X includes the complete FT-X series feature set and enables USB to be added into a system design quickly and easily over a UART interface.
- Fully integrated MTP memory, clock generation, AVCC filtering, Power-On Reset (POR) and LDO regulators.
- Configurable CBUS I/O Pin Options.
- Asynchronous and Synchronous Bit Bang Modes.
- Operates at between +3.3 V and +5.25 V. A nominal operational mode current of 8 mA and a nominal USB suspend mode current of 125 μA.
