Oak Technology Inc. has announced the release of the OTI-9510 52X CD-RW controller that is embedded with an ARM7TDMI 32-bit microprocessor core to provide developers of optical storage products with increased performance and efficiency.

The OTI-9510 is suitable for use in all CD-RW drive applications including consumer electronics and half-height and slimline PC products. It is capable of reading CDs at 52X speed, writing CD-Rs at 52X, and rewriting CD-RWs at 32X speeds using the latest ultraspeed media. These speeds correspond to recording a 74-minute audio CD in <2.5min and writing a 650MB data CD-RW disc in about 3.5min.

The Mt. Ranier standard-compliant controller also provides full support for constant angular velocity operation, which permits faster and more reliable disc writing with significantly quieter drive operation. It also has the company's ExacLink buffer underrun protection to ensure reliable operation.

The ARM7TDMI core has 12KB of on-chip SRAM, 52MIPS of processing power, and a clock speed of up to 60MHz.

The OTI-9510 controller is available now in a 208-pin LQFP priced at $10 each in sample quantities and under $7 each in production quantities of 10,000 or more.
