Sunrise set to ship fastest gate arrays yet
Dedicated NEC distributor Sunrise Electronics is now helping customers to design with the latest 0.25-micron CMOS-10HD family of CMOS gate array products.
It has 32Kbyte of on-chip single-voltage Flash memory and 1Kbyte of data memory.
Developed to meet the needs of a range of motor control applications including three-phase motor control, this device has an inverter timer block with 10bit resolution.
It generates three phases of two PWM outputs (ie three normal outputs and three inverted outputs) and also provides a 16bit up/down encoder timer, 8bit dead time control and A/D trigger generation.
It also includes a number of other standard timer functions, two serial interfaces (UART and CSI), and 48 I/O ports.
Other new features in this device include eight channels of fast 10bit A/D with conversion times of better than 4.8us (compared with 12us on previous parts).
It also has power on clear and low voltage indicators (not available in this series of devices before).
Standard operating voltage of the PD78F0714 is 4.0 to 5.5V, with operating ambient temperatures in the range -40 to +85C, but the device will operate down to as low as 3.7V (with speed derated to 8MHz).
