P89LPC933FDH - 8-bit microcontroller with accelerated two-clock 80C51 core 4 kB/8 kB 3 V byte-erasable Flash with 8-bit A/D converters - NXP Semiconductors
Principal features
4 kB/8 kB/16 kB byte-erasable ?ash code memory organized into 1 kB/2 kB sectors
and 64-byte pages. Single-byte erasing allows any byte(s) to be used as non-volatile
data storage.
256-byte RAM data memory. Both the P89LPC935 and P89LPC936 also include a
512-byte auxiliary on-chip RAM.
512-byte customer data EEPROM on chip allows serialization of devices, storage of
setup parameters, etc. (P89LPC935/936).
Dual 4-input multiplexed 8-bit A/D converters/DAC outputs (P89LPC935/936, single
A/D on P89LPC933/934).Two analog comparators with selectable inputs and
reference source.
Two 16-bit counter/timers (each may be con?gured to toggle a port output upon timer
over?ow or to become a PWM output) and a 23-bit system timer that can also be used
as an RTC.
Enhanced UART with fractional baud rate generator, break detect, framing error
detection, and automatic address detection; 400 kHz byte-wide I2C-bus
communication port and SPI communication port.
Capture/Compare Unit (CCU) provides PWM, input capture, and output compare
functions (P89LPC935/936).
High-accuracy internal RC oscillator option allows operation without external oscillator
components.The RC oscillator option is selectable and ?ne tunable.
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).
28-pin TSSOP, PLCC, and HVQFN packages with 23 I/O pins minimum and up to 26
I/O pins while using on-chip oscillator and reset options.
