Objective Specification
P8xC591
1 FEATURES
1.1 80C51 Related Features of the 8xC591
• Full static 80C51 Central Processing Unit available as
OTP, ROM and ROMless
• 16 Kbytes internal Program Memory expandable
externally to 64 Kbytes
• 512 bytes on-chip Data RAM expandable externally to
64 Kbytes
• Three 16-bit timers/counters T0, T1 (standard 80C51)
and additional T2 (capture & compare)
• 10-bit ADC with 6 multiplexed analog inputs with fast
8-bit ADC option
• Two 8-bit resolution, Pulse Width Modulated outputs
• 32 I/O port pins in the standard 80C51 pinout
• I2C-bus serial I/O port with byte oriented master and
slave functions
• On-chip Watchdog Timer T3
• Extended temperature range: −40 to +85°C
• Accelerated (prescaler 1:1) instruction cycle time
375 ns @ 16 MHz
• Operation voltage range: 5 V ± 10%
• Security bits:
– ROM version has 2 bits
– OTP/EPROM version has 3 bits
• 64 bytes Encryption array
• 4 level priority interrupt, 15 interrupt sources
• Full-duplex enhanced UART with programmable
Baudrate Generator
• Power Control Modes:
– Clock can be stopped and resumed
– Idle Mode
– Power-down Mode
• ADC active in Idle Mode
• Second DPTR register
• ALE inhibit for EMI reduction
• Programmable I/O port pins (pseudo bi-directional,
push-pull, high impedance, open drain)
• Wake-up from Power-down by external interrupts
• Software reset bit (AUXR1.5)
• Low active reset pin
• Power-on detect reset
• Once mode
1.2 CAN Related Features of the 8xC591
• CAN 2.0B active controller, supporting 11-bit Standard
and 29-bit Extended indentifiers
• 1 Mbit/s CAN bus speed with 8 MHz clock achievable
• 64 byte receive FIFO (can capture sequential Data
Frames from the same source as required by the
Transport Layer of higher protocols such as DeviceNet,
CANopen and OSEK)
• 13 byte transmit buffer
• Enhanced PeliCAN core (from the SJA1000 stand-alone
CAN2.0B controller)
1.2.1 PELICAN FEATURES
• Four independently configurable Screeners
(Acceptance Filters)
• Each Screener has tow 32-bit specifiers:
– 32-bit Match and
– 32-bit Mask
• 32-bits of Mask per Screener allows unique Group
addressing per Screener
• Higher layer protocols especially supported in Standard
CAN format with:
– Up to four, 11-bit ID Screeners that also Screen the
two (2) Data Bytes
– i.e., Data Frames are Screened by the CAN ID and by
Data Byte content
• Up to eight, 11-bit ID Screeners half of which also
Screen the first Data Byte
• All Screeners are changeable “on the fly”
• Listen Only Mode, Self Test Mode
• Error Code Capture, Arbitration Lost Capture, readable
Error Counters
