SAN FRANCISCO -- Oki Semiconductor today rolled out a new general-purpose 32-bit microcontroller--based on a RISC processor core from ARM Ltd.--which is aimed at lowering the cost of embedded system designs while easing the system-development transition to higher levels of 32-bit performance.
At the Embedded Systems Conference here, the U.S. chip operation of Japan's Oki Electric Industry Co. Ltd. said the ML674000 series was designed to deliver 32-bit processing at 16-bit cost. The 32-bit MCU is packed with an interrupt controller (with 24 interrupts), two channels of direct memory access (DMA), 16-bit system and counter timers, two channels of UART, a 2-by-16-bit pulse width modulator (PWM), and other hardware functions.
Oki said the 32-bit controller offers designers the use of ARM software development tools along with the wide range of hardware features. This combination makes the chip suitable for industrial controllers, security/surve illance systems, medical instruments, games, toys, digital players, and other devices, according to Oki. The chip is housed in a 128-pin TOFP package.
"Customers reliant upon a wide variation of 16- or 32-bit MCUs can now take advantage of an industry-standard ARM architecture and readily available software development tools at a lower cost," said Ike Saeed, vice president of marketing for Oki Semiconductor, based in Sunnyvale, Calif.
Samples of the ML674000 are available now. In quantities of 10,000 units, the 32-bit MCU is priced at $4.95 each.
