P89LPC9301A1
Description
The P89LPC9301/931A1 is a single-chip microcontroller, available in low cost packages, based on a high performance processor architecture that executes instructions in two to four clocks, six times the rate of standard 80C51 devices. Many system-level functions have been incorporated into the P89LPC9301/931A1 in order to reduce ponent count, board space, and system cost.
Key Features
- 2.1 Principal features I 4 kB/8 kB byte-erasable flash code memory organized into 1 kB sectors and 64-byte pages
- Single-byte erasing allows any byte(s) to be used as non-volatile data storage
- I 256-byte RAM data memory
- I Two analog parators with selectable inputs and reference source
- I Two 16-bit counter/timers (each may be configured to toggle a port output upon timer overflow or to bee a PWM output)
- I 2.4 V to 3.6 V VDD operating range
- I/O pins are 5 V tolerant (may be pulled up or driven to 5.5 V)
- I Enhanced low voltage (brownout) detect allows a graceful system shutdown when power fails
- I 28-pin TSSOP and PLCC packages with 23 I/O pins minimum and up to 26 I/O pins while using on-chip oscillator and reset options
- This is six times the performance of the standard 80C51 running at the same clock frequency
