device numbering conventions

Figure 16 illustrates the numbering and symbol nomenclature for the TMS370Cx4x family.

370

4 0

Prefix: TMS = Standard prefix for fully qualified devices

SE = System evaluator (window EPROM) that is used for

prototyping purpose.

Family:

370 = TMS370 8-Bit Microcontroller Family

Technology:

C = CMOS

Program Memory Types:

0 = Mask ROM

3 = Mask ROM, No Data EEPROM

7 = EPROM

Device Type:

4 = x4x devices containing the following modules:

– Timer 1

– Timer 2A

– Serial Communications Interface 1

– Analog-to-Digital Converter 1

Memory Size:

0 = 4K bytes

2 = 8K bytes

Temperature Ranges:

A = – 40

°C

T= – 40

°C to 105°C

Packages:

FN = Plastic Leaded Chip Carrier

FZ = Ceramic Leaded Chip Carrier

JC = Ceramic Shrink Dual-In-Line

JD = Ceramic Dual-In-Line

N = Plastic Dual-In-Line

NJ = Plastic Shrink Dual-In-Line

ROM and EPROM Option:

A = For ROM device, the watchdog timer can be configured

as one of the three different mask options:

– A standard watchdog

– A hard watchdog

– A simple watchdog

The clock can be either:

– Divide-by-4 clock

– Divide-by-1 (PLL) clock

The low-power modes can be either:

– Enabled

– Disabled

A = For EPROM device, a standard watchdog, a divide-by-4

clock, and low-power modes are enabled
