ST7285C
1 GENERAL DESCRIPTION
1.1 INTRODUCTION
The ST7285C HCMOS Microcontroller Unit is a
member of the ST7 family of Microcontrollers ded-
icated to car radio applications with RDS capabili-
ty. The device is based on an industry-standard 8-
bit core and features an enhanced instruction set.
The device is normally operated at an 8.664MHz
oscillator frequency for RDS compatibility but,
thanks to the fully static design, operation is possi-
ble down to DC, when RDS functionality is not re-
quired. Under software control, theST7285C may
be placed in either WAIT, SLOW or HALT modes,
thus reducing power consumption. The enhanced
instruction set and addressing modes afford real
programming potential. In addition to standard 8-
bit data management, the ST7285C features true
bit manipulation, 8x8 unsigned multiplication and
indirect addressing modes.
The device includes an on-chip oscillator, CPU,
ROM, RAM, 62 I/O lines and the following on-chip
peripherals: Analog-to-Digital converter (ADC),
two industry standard SPI serial interfaces, a Seri-
al Communications Interface, an I2C interface, a
digital Watchdog Timer, two independent 16-bit
Timers, one featuring an External Clock Input, and
both featuring Pulse Generator capabilities, 2 In-
put Captures and 2 Output Compares. RDS Filter,
Demodulator and GBS circuitry for car radio appli-
cations is also included.
NOTE: FOR THIS DEVICE, SGS-THOMSON
CAN ONLY RECEIVE MOTOROLA S19 FORMAT
FOR ROM CODES.
