Cypress Semiconductor has withdrawn its offer for Atmel, the second failed attempt by the company to acquire a chipmaker this year. Cypress submitted a bid to Atmel's board, but dropped it after the offer expired, Cypress said on Monday.

Atmel makes small processors called microcontrollers used in a wide array of electronics. The chipmaker agreed this month to be bought by Dialog Semiconductor Plc for about $4.6 billion.
