The ADSP-21991 extends the ADSP-2199x mixed signal DSP product family by offering increased memory integration compared with the ADSP-21990. The ADSP-21991 integrates a 160 MHz, 16-bit, ADSP-219x DSP core and an 8-channel, 14-bit, 20 MSPS ADC (with dual sample-and-hold amplifiers for simultaneous sampling). Additional mixed-signal integration includes a precision on-chip voltage reference, and a power-on-reset (POR) circuit. Various control peripherals are provided for single-chip solutions for embedded control and signal processing applications.

EMULATOR-USB & HP USB ICE
USB-Based Emulator and High Performance USB-Based Emulator
Features and Benefits
- Full speed USB 1.1 interface enabling download speeds of up to 150 KB/Sec (ADZS-USB-ICE) or High speed USB 2.0 interface enabling download speeds of up to 1.5MB/sec (ADZS-HPUSB-ICE)
- Background Telemetry Channel (BTC) support enabling non-intrusive data exchange at up to 2.0 MB/sec (ADZS-HPUSB-ICE only)
- 1.8V, 2.5V, and 3.3V compliant and tolerant
- Support for all ADI JTAG processors and DSPs
- 5V tolerant and 3.3V compliant for 5V processors and DSPs
- Multiprocessor support
- 14-pin JTAG connector
- 3-meter USB cable for difficult-to-reach targets
- CE-certified
Product Detail
The plug-and-play architecture of USB allows the emulators to be automatically detected and configured by the host operating system. It can also be connected to and disconnected from the host without opening the PC or turning off the power to the PC. A 3-meter cable is included to connect the emulators to the host PC, thus providing abundant accessibility to hard to reach targets.
The HP USB-based emulator also supports the Background
Telemetry Channel (BTC), a non-intrusive method
for exchanging data between the host and target
application without affecting the target system's
real-time characteristics.
