ProcessorPM® - Voltage Supervisor, Reset Generator & Watchdog Timer Functions in a single chip
- click image to enlarge
Imagine a processor support device that integrates all types of reset generator ICs, voltage supervisor ICs and watchdog timer ICs. That is what you get with the ProcessorPM™ device. The ProcessorPM device integrates six precision (0.7%) programmable threshold monitors that can be configured to monitor any supply rail from 0.67V to 5.7V, a 16-macrocell PLD that can be used for generating reset signals and brown-out signals and four timers for reset pulse stretching, de-bouncing reset switches and implementing watchdog timers. This device can be programmed in-system through JTAG and the configuration is stored in the on-chip non-volatile E2CMOS® memory.
Key Features and Benefits
Low-Cost Programmable Mixed-Signal IC
- Reduced cost ProcessorPM integrates supervisor, reset generator and watchdog timer functions and costs as much as a supervisor IC
6 Precision Programmable Threshold Monitors 0.67V to 5.7V
- Smaller BOM – One chip replaces multiple factory set supervisor ICs and resistors
- Increased reliability due to increased monitoring accuracy
16-macrocell PLD to Integrate Various Logic Functions
- Standard solution – Design-specific logic functions required to support wide range of processors and DSP
Five Configurable Outputs with Programmable Functions
- Reduced number of ICs in a system – Single chip integrates multiple types of functions such as reset generators, supervisors
Four Programmable Timers
- Reduced number of ICs on a board – One chip to integrate watchdog timers, resistors and capacitors
24-Pin QFNS Package
- Smaller overall circuit board area – 16 mm2 area replaces many ICs, resistors and capacitors
-40 to +85ºC Operating Range
- Can be used across commercial and industrial applications
JTAG In-System Programmable
- Reduced manufacturing costs
ProcessorPM can be customized to implement supervisory functions specific to any processor or DSP.
Lattice’s PAC-Designer® software, a PC-based software tool, provides simple and intuitive pull-down menus for configuring all programmable features of the ProcessorPM device to implement support functions for a wide variety of processors and DSPs.
